I've been watching your videos for a long time on my television and I never could figure out how to comment, but now that I can, I feel the need to thank you for all of help your videos have given me. God bless you sir. Thank you.

You are the only one thus far that has so much detail and educational content...!!!!thank you...!!!! 👍👍👍👍👍

Like what you said about defensive driving, Been hit twice both while I had right of way and driver blew red light , then stop sign, I slow at every cross and ride much more aware now.

You especially have to ride like you're invisible on these because people see a bicycle and assume its a normal bike and think they they have time to pull out I've almost been run over by a tractor trailer that was at a stop sign because of this, he started moving as I was directly in front of him, it wasn't his fault nor was it mine but you have to be VERY careful when riding these

Hey, great advice on filling the space in the chain cover. About the exhaust lubing the chain, not a bad idea except the un burned old is not the only thing that will drip from the pipe. An automatic oiler isn't hard to make and can be set to drip very slowly. Just have to remember to open and close the valve at the beginning and end of each ride. I don't know if o ring chains are available in this size, but they only need to be cleaned once in a while. The way we used to lubricate they non o ring chains for racing many moons ago,,, Heat grease in a pot and immerse a chain in it. When the grease thins out, it creeps in between the pins and rollers where it's needed and thickens up there when it cools. Was the best "trick" for keeping lubrication in an abused chain for a long time. Enjoyed your video and have subscribed.

You've helped so much when it comes to deciding if I should get a bike engine and now that I've been watching your amazing vidoes I see that maintenance is easy and it's pretty simple and fun. Thank you for the great videos. I love them so much.

Very good videos. Very informative just all together really good professional and well done

I’ve had my motor for two years and runs fine haven’t changed cylinder head clutch pads and stuff like that

Love your videos man great job on everything you do im your biggest fan thanks for all your expertise and knowledge

ive been watching your channel for a while now. i had one of those 80cc anbull engines that came in but the engine came seized and the clutch was broken lol. i have a 50cc being shipped soon and im super excited to use it ! im thankful for these videos youve made. thanks a bunch!

Recently took a 112 mile trip from buffalo ny to olcott ny and back broke the engine in nicely

Loving my two stroke right now

Thanks for the tips very useful i'm from puerto rico in my fatbike i got a seeutek and runs great thanks again👍👍💪

you made a good point about being defensive, alot of people do NOT think!

Regarding what tools/spares you carry with you: You didn't mention a 14mm socket and some kind of wrench/ratchet wrench, and ABSOLUTE MUST! I went on a long ride during one of the hottest days of the summer two years ago. Well, I brought every tool/part you could practically need with me, EXCEPT for a 14mm socket and wrench. My head bolts ended up coming loose (forgot to tighten them after break in, so STUPID!) and I blew a hole in my piston, was pretty scary, but the worst part was pushing that 70lb bike for 5 miles to get back home in 110 degree heat. SO KEEP A 14mm SOCKET AND WRENCH ON HAND AT ALL TIMES!

On the note of riding like you are invisible, (which, btw, is exactly what you should do) you should also ride like EVERYONE can see you. I built bikes for my cousin and i, (we live in a decent sized town/city in Wisconsin) while riding around, a car came up from behind and was tailgating my cousin really hard. (Speed limit of the road was 30 mph, we were both doing about 35mph and unable to physically go any faster.) Causing him to run off the road, but not before that car cane with in about a foot of his rear tire. He slammed on his brakes so hard just to prevent from crashing that he locked the rear brakes (v brakes, the arms tightened and bent so they held the wheel) and bent his rear wheel. Ride safe out there.

well put together video and rides! I'm waiting for my first kit to arrive a YD100 , I have been filling in my knowledge gaps with help from your likes. I'll be back roading on mine, so it's primary goal is reliability tips and tricks are always welcome .

Oh, that last question is interesting. Reminded me when I was young, and I over filled the oil in my C90. The seal on the gear selector drum is right over the front sproket, so when it blew off because of excess oil, my chain was lubricated 🤣

Great video and yes I like this kind of videos very informative one advice that stick to my head was to drive like if I was invisible great tip

Your videos are great

I bought a universal hydraulic disc brake and adapted it to the stock cranbrool wheel and welded a bracket to the original fork works great!

Good info! Guess that I've been lucky, as I've had Pepe (my motorized bike) for over 13 years and only a leaking intake tube and weak chain needed attention-John in Texas

I am on my 7th build.. the first motor failed me because the mounting bolts vibrated loose while going down the road and one bolt snapped off when the motor turned sideways. The other 6 bikes all still run fine and my family uses them on a daily basis to goto work, store etc.. I have learned it helps to check bolts often, use liberal amounts of locktight and try to keep the motor in its comfort zone, (8/10 of throttle) to keep things running very smoothly. I have yet to build a 4 stroke, but that is coming soon.

Good vid,and great points.I like the Q&A areas too.I don't run my motor wen I get on a sidewalk for traffic safety.I Never believe someone sees me,and watch out expecially for people turning right.They look left,but almost Never right before turning.@$25 for new cylinder and ring set of Ebay.I found 1 for $23.Happy Trails.

I've built 2 kits, so I'm definitely not an expert, but my bikes get ridden, a lot. After the first few miles I tightened them up, then they were fine. Full disclosure I did replace the crappy hardware with grade 8 stuff.

Beautiful Vidio Sir! Very Informative! earned my sub

I like the experienced advice. It's good educational content. I'm just beginning to research motorizing a bicycle and all these tips help. This video potentially just saved me and others from some serious headaches and stress in the future. Thanks 👍 To answer your survey: yes, make more experienced tips and tricks vids. They help people.

I like your endurance video this is good too I just have a 2stroke I built and am always still building and like seeing them healthy enough to do that

Couldn't agree more if your going 35 mph on a bicycle with 2 stroke engines you better have you're wits about you.i have a little mountain bike with the 49 cc really cool I built it from scratch. Along with a better bike I recently picked up another complete one for 50 bucks. My first bike has a little more than 200 bucks My first build I am mechanically experience and frankly I grew up race deserting motocross. Open class only so these cute little things are nothing really but fun.i plan on on building a collection 80 cc 100 cc and a 4 stroke model.when I graduate to a high speed road bike I plan on using one of those cool frames with the built in tank I have seen some gorgeous ones that are out together sweet with the backseat and years 70 plus mph but for now I going to build mountain bike style and get more experience in our these little rice burners under my garter belt haaa.You provide a tremendous amount of information on these things and I sincerly appreciate it. Take care

Shouts outs from Erie Pennsylvania

Good video and info. Subscribed

I agree on your assessment on the rag joint. The alignment and maintenance is the key to it lasting

Compared to the other guys doing motorized bike videos, you're the most engaging. You don't even sound like a man from Louisiana.

So today I went a got the exact same bike with a cheap engine kit on it for only 100 bucks! The bike had its tags on it and the bike never even got ran through it’s first tank of break in oil even yet! Only thing that was wrong was the throttle cable got pulled through the plastic throttle tub but luckily I had one from a minibike I had that worked and now I have a awesome bike to cruise back roads around me

Havnt tried oil chain from exhaust mainly cause try to keep oil from rear tire. Learned that lesson riding motorcycles. Also chain catching...,I tilted my motor forward so that top of gear case was further away from chain and have had no problem since. But understand not every solution across the board. But have built 2 stroke, 4 stroke and 1000w 48v ebike. So i have learned many lessons the hard way. Biggest upgrade in my opinion was wheels. My spoked wheels had to be trued every other ride and just got sick of tasking tires off n on. So i got some mag wheels and i love them. Durable, sprocket mounts directly to wheel and disc brakes were no problem to install. after i made my own adaptors. so if i can help with Anything would be my pleasure.

Just thought you'd like to know a garage door opener that uses a chain to operate it will work on the bikes. It's a 415 chain. It's a nice long length too. I see these in dumpsters all the time.

Exhaust oiling the chain. Back in the day Harley routed the engine breathed thru a tube that exited over the chain.it worked on my 74 flh. But then the eco crew did away with vented motors. What's old is new,lol

The oil from the exhaust lubricating the chain is a really good idea!!!

The thing I love most about this video is the question at the end, that's something I would like to know

On your seeutek motor take off the fly wheel cover clutch plate and spring. Then loosen clutch cable and it will reset your clutch arm.

Hello All..... I built a custom 80cc and had to CUSTOM bend the exhaust in order to clear "Leg Space". A bonus was that the exhaust oil blasted onto the chain while riding. Matter of fact, it lubed the chain so well that the master link came apart and the chain just slipped off to the ground. BTW> I was at 40 MPH. Talk about Dumb Luck with NO damage? Anyway, Just thought I would share this with you all and PLEASE don't run your bikes passed 50MPH !!! Mine does and it's NOT fun anymore at that speed.... Talk with you again, Phil

I see the way you ride and interact with the bike. I just picked one up and plan to get quite a bit of use out of it. And I'm hearing horror stories about using them as regular commuters

On the fork swap....Myself I used a set from a junk bike.... I had to use a cutoff wheel and trimmed the top and bottom of the tube for the threads to fit the top locknut on.... Just make sure it is an even cut and clean the edges for the bearing cups to fit back in the tube

Nice Video!

Ran one only one rim with rag joint for 12 years, maybe 5000 miles. Retired it only because last time I had it trued, they said that all they could do with it. Got hub adapter, broke spokes, punctured tube.. A nice slime tube 😢. A - I didn't got back and check it B - Grease found its way between hub and adapter.

You just gotta like at 80 miles an hour and a tractor trailer just got into motorized bicycles love the sport thank you

Thank you for making these videos, they're awesome!

Eh fender tip take a piece of pvc pipe split it with a saw and heat it up and bend it around a old rim, will have to clean up a few waves but they would great as full fenders

Don’t sell yourself short! Fort nine does have high production value, drone shots, and a chase crew to put this whole thing together. If I wanted to watch the Discovery Channel, I would. The content you gave in the Q&A is far richer. They wax poetic about Moby Dick, and Ishmael, blah, blah , blah! I subscribed to your channel, not theirs. Keep it real, and we will keep watching. Roll on brother 👍👍

My bike has all the street legal stuff, even turn signals. I still been hit 3 times. I ride in the street and always give cars/trucks the right of way letting them go around me... but they don't always move over far enough so they end up clipping me with the mirror or turning into you. there are bad drivers, some that actually hit parked cars and run up poles.

I have also heard of the exhaust system having garbage in them and it gets sucked into the cylinder.

Gotta concur regarding rag joints. I have one on one wheel, and a Billet Adapter on another build, and truth be told I think I trust the rag joint more. Just something about the nut bushings on the adapter against the spokes under torque...I dunno, I may put a rag on that wheel too...

Make sure you ten your tensioner to the bike frame a bolt or a pain in the frame where the bolt tensioner is for the chain so it does not move and take your spokes out

The first engine I ever bought had the piston installed backwards and both rings were busted when I finally had to overhaul it. I check the piston every time I get a new engine now. It’s 50/50.

They sell a little peace of metal called a "motorized bicycle chain stop" on ebay that bolts the side cover preventing chain lockup.

24:00 I had it twice because I didn't tune properly, got it started and going but would immediately sputter out, and going fast on a heavy bike when that clutch is fighting back... it was enough torque to bend the stock tensioner bracket, and the I guess the shock of it rippled up the chain and got it stuck.

when my motor kicks on , what do i need for the peddles to stop moving? i believe its a chain to goes from the peddle to the motor... any ideas????

I agree. Bought a adapter 40 tooth. Like rag adapter better👍

The 415 stock chain that comes with the engine kits is more than long enough for 29" bikes. You still have to remove about 5-7 links to have the correct length of chain.

Hey brother,so I picked up a yd ,oz reed,and a 21 mm pwk,my question is how do you do "piping" to make it all work?I mean from intake to carb.Thanks for any help.I heard you mention p.v.c. once I think.

Words of wisdom 🙌

Regarding oiling the chain from exhaust, as far as I know the carbon/ash and heat from exhaust harms the chain links causing excessive wear and shortening the chain live. This I know from old motorcycle guy, never tried or seen this on a motorized bike. For the sake of experiment I guess it's worth trying, I let you know if I ever do.

The ears on the wrist pin clips get knocked off. I lost 2 engines that way. the cure is using clips without ears. Treatland has them from Wiseco for about $5 with shipping. You have to cut a groove in the pin area so you can get a pick under them.

those older style cylinders have poor quality chrome in them< i swapped over to using the new style g4 cylinders. they have better chrome in them and better port timings

Yes I actually do run my exhaust where it blows on my change oiling my chain however you have to have a chain cleaner permanently mounted on it otherwise with the excess oil on it the road dirt gets up on the chain and causes damage to the chain and gumming up your sprockets inside the motor housing other than that it is a lifesaver especially if you ride in very wet areas my chain has never even had surface rust on it

Lol !!! You couldn't be more accurate. We call that senero being "Dead Right" ! When undoubtedly you're in the right, but now you're dead !!!

I think the large gap around the chain sprocket on the engine is so you can put a larger gear on and still have clearance.

So, what is your favorite bike frame? And what is your favorite engine?

I've been riding the same two-stroke 80cc motor for 11 years with a rag joint on it same rim on the back same rim a huffy stock Chinese rim and I tighten those nuts every 10 hours riding it I've never had any problem

Bro I really like just hearing the sounds of the tools and stuff without music or anything

Does anyone have any experience with the bbr tuning stage one 2 stroke kits

Hey br i like ur videos...what do u think is my best bet on a rear wheel..obviously i would like to get a hub adapter but i at least am going to go with 12 gauge spokes.. my bike is a Yukon Giant 44 to carburetors stock I do have a banana pipe on it not a full expansion chamber but it in Access one and runs a lot better with it curious what you think as far as wheels go bro

I like the points you raise about chain lubrication, tension and it folding up in the trans. Chain tension I would imagine could be solved with a 2 stage spring tensioner... fancy yes but I'm gonna make one, essentially like a miniaturized long travel shock absorber in a guide. The "fill the space" epoxy puddy is a great idea too, but the machined cover would be ideal. Compromise and go get a guide plate welded to the inside of your cover? Automatic lubrication would be great, but I would worry about an excess buildup gathering in the trans (especially with the cover chain guide) or worse... on you. Not sure how much the exhaust leaks honestly, my only frame of reference I have is messy nitro RC motors. I'll be ordering my 1st 48cc 2 cycle kit (IL legal) next week, and your video is quite informative, thanks!

How do I make my clutch engage to start my bike ? It just carry’s on free coasting instead of starting ?

Love your vids man. Do yourself a favor and buy a 1/4" drive Ryobi impact driver and some sockets. It's cheap and is more than good enough for this type of work. You won't regret it!

Exhaust near or blowing on chain I've seen only on motorcycles not bicycles. It heats up the chain & makes them look real dirty but never seen anything go wrong. I've also seen a blow by hose on 4 stroke go on top of a chain.

Once you take the forks off you will see what size head tube is but older ones typically had smaller tubes and the new ones have larger sized head tubes!

built 2 fat tire bikes and 1 standard bike using 56 tooth and had to add more chain. no big deal. but have some around so you don't have to wait to ride, peace ride family

My engine cuts off whenever I engage the clutch I just did a complete engine overhaul on a phantom 85 any ideas why it shuts off when I pull in the clutch

Even without the motor on a bike you still have to watch out it might just be me as I’m a young boy but without a motor but still I’m doing like 30 km/h on a slight decline and people don’t look properly when turning right I actually have a scar from a car hitting my bike a year ago and started watching out for this stuff

what size are the gungeon pins on these engines? one of mine flew! off today. didn't even hear it land.

Ayyy I’m from Indiana!!!!!! At least that’s what it sounded like you said 13:55

I had a motor do the.....I took the carb filter completely off due to more power, I rode it in rain and on dusty days, the engine lasted 7 months before it died. Mine starting making scary noises then lost power....it started but died soon as you gave it gas....the cyl walls looked like a grinder was ran through it.

I added a full electrical system to my 49cc 2 stroke: I have head lights, tail light, brake light, blinkers, a horn and even a phone charger. My problem is that because of a bad fuel/oil mix I caused my motor to seize. I replaced the cylinder, piston, got a high performance head and carb. I have compression and my multimeter says I should have spark (new spark plug too) but as soon as I let out the clutch it locks up. Any ideas?

Be careful if you decide to try your chain lube idea using the exhaust. It might infringe on fords automatic Undercarriage system for lubrication of external stationary parts system. Theirs uses leaky oil pan/valve cover gaskets, and the venturi effect, combined with any crankcase pressure to atomize the hot lubricant while driving, and the force of the air at driving speed to distribute the lubricant across everything. Your idea of using the unburnt oil already coming from the exhaust is a far superior automatic lubrication solution though in my opinion, because since these 2 stroke engines do not have a wet sump where engine oil is stored, only a "moist sump" (lol) where the oil/gas mixture passes through the case to lube the bearings. You wouldnt have to install the red flashing "replace engine now" light, that always comes on after your U.S.L.E.S.S. lubrication resevoir runs dry while driving, since it shares its supply with the lubrication system for the engine internals, and yours uses what would end up being wasted oil anyway. They are similar systems, but i'm no patent lawyer, so take my comment, as well as the (hopefully obvious) satire with a grain of salt. TL:DR, I think your chain lube idea would probably work well, but maybe too well. It will almost certainly be messy. I"ve had an ingrained negative outlook on Ford vehicles since I was old enough to drive. Love your videos BTW. I just had to toss in a little humor since I've watched quite a few of your videos now since being bitten by the bug, and you've helped a ton with some decisions on what to buy, and what to stay clear of. Keep it up. Sharing your experiences is helping someone somewhere. I'm honestly interested to know if you ever tried the chain lube idea though, and if it resulted in a black stripe down one side of your back or not :-P

Where are you from? I might need your help with a rebuild on three motors and how much will it cost to send them to you

A remedy for a slipping adapter is to install it on the shaft and if both sides touch both sides need to be shaved till you can see small spacing after that use a pin punch and tap it with a hammer to roughen it up the inside and also all around the rim shaft and problem fixed

Hey, that last question caught my attention. On my Huffy Cranbrook, I have an El cheapo banana pipe, and it does just that. It does actually lubricate the pedal chain, unfortunately not the drive chain, but yes, it works great 👍👍

I agree on FortNine, their production quality is insane.

Thats a chaintastic idea

Get rid if the inline fuel filter if you have one in your tank , increases flow and make sure your ratio of oil is tuned to your bike where the bore and head is not black and spark plug is coffee looking

Been hit twice and gotta admit hes right both times could have been avoided. One time i was late to work forced to take the bike with basically no brakes.

Holy crap did u make me laugh all of my motors have been second hand I'm sorry to say virtually no milage because of the exact scenario you described either a wheel fell apart or some other misfortune I got the good end of the deal someone or several someone's realized a crash at even 25mph sucks hard and have gotten 6 motors this way thanks for letting people know that these aren't for the average person or kids they vibrate a lot and require a lot of carefull maintenance to be safe thank you!

I’ve seen 48ccs with the same engine parts for 2+ years, I guess some just tend to last longer than others, I’ve seen a cheap 66cc last for 30 minutes before blowing up these things you just never can tell.

I know you're probably busy but I'd like to ask you what motor kit to buy for my Mongoose mountain bike I'm pretty sure it's a 26in I'd like it to have decent amount of speed as I live in an urban city like area I'm not trying to spend a lot of money but I don't mind standing at the same time to get the right motor please give me a recommendation whenever convenient thanks a lot and good job on your videos

Amazon sales them. The cnc chain anti. wrap up plate. Butt u have 2 drill

Hey how can I fix my muffler bolts that are broke at stud how do I get them out so I can put a new one on let me know

Are you running no chain tensioner in this video??? Please respond I'd like to know if Engine mount style or running no tensioner at all would work better than the stock one obviously right?

How can u tell all the motor’s apart from each other. Theres no casting numbers on ether of the 2 i have but one has smaller one pice head an other has bigger 2 pice head

Only crashed once ever and it was because of slick roadways... And as for the chain tensioner issue drill a hole directly through the middle of both cover plates and bolt it directly to the frame it will never move again.
