I like this video. These tips are almost priceless. I made many of these mistakes back in '07 on my first kit. This is my second build now it's 2023 and I want it done correctly and well. Last time my older brother (mechanic type guy) did most of it. I'm doing it all by myself this time. This is the second time I'm watching this video and saved it to a favorite folder.

This is incredible ! I already have experience with these engines, but there are some tips that i didn't even think about in the first place ! continue what you're doing !

I’ve seen countless tutorials about these because I just got one and this is the most in depth and best one I’ve found so thanks

Had bolts come out of the exhaust twice. Installed two studs with 680 green locktite .. Used Three jam nuts . Locktite with red on the last jam nut. No more problems.

lol I have the same o ring thing... thank God! I'm about to do my first build and I'm using your video as my go- to lol thanks!

That’s better than I expected, professional

Thanks a bunch for sharing your knowledge. You've helped me out a lot.

I build motorized bicycle but i still learned a couple of new things ty great video.

Great video with lots of useful info. I would add to check the spark plug gap. I've encountered more that one kit with the gap way off. My first build had this issue and after 1 hour plus of troubleshooting I had an "Aha" moment and checked the plug gap. Once properly gapped I was off and riding with no other issues. Also, after 5/10/15 hours of operation check all bolts again as the heating and cooling cycle and vibration tends to loosen some of these.

Chain guard is very important, its not to protect your feet when your chain breaks, but prevents your pant leg from getting caught inside the engine spinning a few thousands RPM, and preventing it from pulling your leg into the spinning gear which would shred your flesh like blender. The chain tensioner is the killer. Run without one before it gets caught inside your spoke while riding 30 mph, stopping you like a giant branch got stuck between your spokes.

Good job....very informative!!!

You're a man after my heart using all of that grease and oil I do the same things LOL

This bike frame I've got, well I'm going to have to mod the engine mount on the exhaust side. The crap they included won't work in my case. But I think I've got it figured out. Just waiting for the parts store to open. That grease... yeah I'm picking that up! This is the a great video. Thank you 😊.

BEST FUCKIN VIDEO ON KZfaq 🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨. ESPECIALLY THE SUPER GLUE TIP AND GREASE IN THAT DAM CLUTCH HOLE ⚠️⚠️⚠️⚠️⚠️.

SO. MANY. GREAT TIPS! I dont watch many 20min videos all the way through

Thanks for the video, my brother still insists on riding these cheap motors so here we are watching your video, i remember messing with them over a decade ago before i decided to go electric.

POST MORE I NEED MORE OF THIS PLEASE POST MORE

For the exhaust, Mount the exhaust pipe with the black Allen screws that you can get at home Depot. May even be able to get away without using loctite, with loctite definitely not coming out.

IM BACK 😂😂😂 nice video bro

Very informative build! This is a 2 stroke.

Great tips, sir!

16:23 lever seems to be meant for dual brakes. I bought dual brakes lever, which highly recommend, it looks like that. One lever pulls front and rear brakes

Nice video. Q: what metal is stronger for this type of bike ? Chinesium or unobtainiam ? Q: what weight magneto oil should I use for this engine? Should this oil be measured in metrics cc , or USA standard ounces? Im a newbie so any info will help. Thanks

An easy way to keep the engine from turning over is a few feet of small rope in the cylinder through the spark plug hole. Remember to leave a little hanging out. Old mechanics trick

Always go in a star pattern tightening down your sprocket no matter tight you think they are never never never never never go in a circle at any time

Love your video man but what do I do for the throttle? My bike has a twist grip shifter on both sides and I’m not sure if I should just cut it off or what.

loctite doesn't do well with heat, that's probably why they come loose on your exhaust

Great tutorial

Great video. Number one tip. Bike will fail not the kit. Mine's on its third bike.

ive got a onex/onyx 26" was thinking of motorizing it but want rear wheel free wheeled not just when you take off the mechanical lock but adding the rim and rear brakes either pads or rotors what say you

Hey man I just found your channel you been real helpful to me I just got my second DWI and I can't drive so I'm 54 years old and I'm riding a motorized bike I got old huffy that I've had a motor on for a couple years and it set up I've got some bunch of rest in the gas tank it won't start but I think accidentally taped that white wire to the frame with my other wires today too so you think both of those could be the possible reason why my bike won't start appreciate any suggestions you might have thanks I clean the tank out today I'm going to I'm going to clean the carburetor tomorrow and I've already done taped my wires and separated that white wire so hopefully that'll fix it appreciate you

chain guard for pants?

How does the engine cast ?

I had the machine screws come out of the exhaust. After using blue lock right I had no issues.

Awesome vid dude. Any issues with the chain hitting the case inside the front sprocket?

Excellent information with one exception. Do not use WD40 for lubrication. As it ages , it turns into a sticky resin which no longer provides lubrication. WD40 is excIellent for holding on the rubber grips, but instead, use TriFlow for throttle and cable lubricant.

What size engine are you using and how fast will it go? Thank you.

What size bike frame did u use?will 17.5 inch frame work? Mountain bike

YOU NEED A CHAIN GUARD!!!!! If you dont wanna make the stock one qoek gwt a different one. I knew someone who died because his chain snapped and cut his leg, he bled out before paramedics could get to him. Use a chain guard or dont do this at all your life is more important than this.

your explanation so funny, especially the useless chain guard hahaha...

What grease do you recommend using

What motor grease did you use?

I have a fat wheel with disc brakes will the rear gear affect the disc brake 26"4.0 wheel

What bike/wheel size would you recommend I’m a small male but want to put a few custom parts when I get mine: carby, spark plug, and a few others?

i notice the bottom leg of the magneto is touching the rotor magnets, i recommend sliding a piece of paper in there and re-tighten the screws

The throttle grip is 2-pieces. The black grip slides on to the white plastic cylinder so instead of gluing it you can pull it apart and clean the inside of the grip with some dish soap and if needed you could wrap a couple inches of electrical tape on the plastic to make the fit a little tighter, OR you can replace the grip with any bicycle grip as long as it's stretchy enough to fit over the plastic piece, which is slightly larger than a normal handlebar.

What wpuld be the issue if wires are connected together properly and you get no spark?

what is the bike in the video?

hey dude whats the best cheap kit? i got like 130

I wish I was a kid again !

I just got my Engine. Couldn't help but throw the whole thing on in one day. Anyway, I've used some of your tips. But I'm not quite sure of the fuel ratio. I found on some websites and google. Those say 16:1 for the first three gas tanks. And then 20:1 after its broken in. Does that sound about right?

Idk about the wd40. It could eat the plastics. Silicone dry lube or graphite is best.

Hey how big the the distance from the top to bottom of the gap where the engine goes??

Grind the tops off the head nuts so they don’t limit the tightness of the nut.

is that second hole on the hand clutch lever for a brake cable so u dont need 2 levers on 1 side of the handle bar?

What do you do if you have something like your gears, middle gears and your seven on the back right side and then a disk your freak on the back left

You didn't talk about any mounting tricks even though you did something less than standard. Maybe it's a good thing for a part 2. Mounting shenanegans.

I don't understand why some of you guys or really alot of you have problems with the exhaust bolts working loose and or falling out....IV been building these little bikes since 2019 but IV been building and racing cars trucks,, motorcycle,, 4wheelers and I ride my motorized bicycle every day back and forth to work and I never have or have had problems with my exhaust bolts working loose and or blowing exhaust gaskets....but I do make sure to get them tigh and I retighten them after they get hot and cool down and I also use ultra gtey silicone instead of a gasket and I don't have any leaks at all ...I don't use any lock tite at all but it does work very well and I do mean very well if it's been cleaned properly....if you use red lock-tite and it works back loose it's because you did not clean and prepare your surfaces properly....

Just mounted everything on a 100cc it's the same as yours but the chain is rubbing together so I can't move the wheel :/ I removed some chain links but maybe installed wrong

Thanks

I've always heard to use Lithium grease instead of WD-40 because WD-40 evaporates. Would lithium work in the throttle cable or will that gum it up?

Only thing I wouldn't have done in this vid is pull the throttle pin out.. extra measure to make sure you have a perfect pull

40 .1 gas start to death on my 100 cc rite out the box really don't have a big problem with it

I need help asap. I don't know what kind of grease to use. I have permatex ultra slick oil assembly lube, but I don't know if I can use that instead. Please inform me of what to use, it's my first time building one of these.

Can you do this with a Ninja 250 motor?

Do you have to use the pulley

What grease did you use

what is the size of spark plug tool? 16-18mm or 18-21mm?

i have two running motorized bikes and they use bmx chains. thinking about it, i just put a new chain on, and the old one was very stretched, so maybe im wrong to use bmx chains because stretch.

I found the sprocket pretty much impossible to get aligned in the center in the chain no matter how much I fiddled with the bolts. I'm resigned to simply hope it doesn't fall off.

White wire is for headlight or 5v usb

Always install chain guard it only takes once and then you wished you would have

how to set how much gass can go n the carb

What is the best motor for traveling. Like 20 miles a day.

Seals-all is gas and oil resistant and the fuel valve should never have to be removed anyway

Can a better magneto be found which has a higher output so it can power lights?

My crank hits the exhaust any tips

i bought a tube of red lithium grease last week i hope that will be ok

Yup...I was watching cuz of the wiring

You got a link for the kit?

My muffler exhaust gasket always sprayed oil residue everywhere

What kind of grease is that ?

I built a motorized bike using that exact frame and color, and have gone through 2 motors and thousands of kilometers. The frame is still solid. The wheels have been replaced several times however. The stock cantilever brake up front is quite powerful surprisingly.

I counted how many you cut with the chain breaker it was 6 pins up is that how far I should break the chain

Which bike frame is best, steel or aluminum?

What type of grease where u using ?

who was the bike made by? i never saw that brand

How to stop gas tank studs from cracking tank causing leak?

WhT engine is it 4 Cy le

Chineseium!!!! 💀 😂

i have a vintage gt agressor bike it needs no chain tentener

Those "Phillips " screws on the Magneto frame are not Phillips screws. They are J.I.S as indicated by the dot on the top of the screw head. Get the proper screwdriver as the Phillips head screwdriver is designed to slip on the head.

Drill a hole in your handlebar to secure throttle. They will slip

Always use a filter on a gas line

Honda has a line of small motors. Anybody ever hear good or bad things about using one in a bike?

I wish I was 14 again !

Ty. Just bought 1. However im a dumbass & it don't fit in the bike i bought. Im an idiot. Looking for your other vids

1:42 chinesium😂

Hwy so i just bought a kit

Soapy water in spray bottle works great on hand grip oil will stay slippery all bolts best with flat then lock washer grease for clutch / gear box ok lithium white grease best on cables chain tensioner most suck n give problems if can remove 1-2 chain links and reconnect with back plate n clip
