Order of operations from a qualified mechanic is read the plug, look for detonation (tiny metallic balls), adjust the float if needed, adjust the low speed, install a proper main jet, adjust the needle clip position. In that order!

are there more than one jet that you two are calling it the "main jet"? Is there a secondary jet in those carbs?

@@jgbelmont What is the float? Going to have to search youtube for whatever that is and how one adjusts it.

A float is a plastic floating piece inside of the float bowl. When fuel enters the float bowl the float rises, pushing a small pin into the top of the carburetor. The float does that to basically make sure the engine is getting the right amount of fuel. When tuning sometimes you need to adjust the float because it could give you the wrong amount of fuel.

@@WhiskersTheFish makes sense now. I was wondering exactly how that needle disc adjustment worked too. Ok so that’s little area of the carb is the float. Thanks for clearing that up. Are there multiple jets?

It is the same motor as mine, I believe your motoos is on the blue cranbrook if I am correct. I hope you are ok with mentioning your channel in the video.

LA Hover I plan to build a 4 stroke bike this summer around my birthday time with some money I am saving up. Motoos makes a 4 stroke and it has good reviews so I will get that engine from amazon and I was thinking of putting it on a huffy cranbrook. What do you think? Are the cranbrooks good bikes? I heard they can fit 4 strokes, what is your opinion on that?

Thankyou, I guess you would call this a budget bike because the engine and bike combined were only $250. That was all the money I had so I just got a used bike and amazon engine.

Funny enough the day after this the bike would not idle at all. I turned to Reddit and with some help I’m going to be changing the float level. I’ve been told that will help it idle and with changing jets, float, and clip I can get it tuned perfectly. It’s been 3 month of frustration tuning this pipe.

@@WhiskersTheFish This is common when you add a chambered pipe. Especially a one size fits 1000 motors type lol! Your jet size will always almost increase a bit. gas level in float thing never got how it's suppose to fix that kind of issue that is more of a no gas to run kinda thing. Your runs fine. Just needs to be set to a leaner setting with a slightly bigger jet to maintain correct air to fuel mix to run correctly. pz16 would run that bike perfectly out of the box pretty much with factory settings. seems common that pipe

Like an Example! When I added one of the MZ6 clone pipes to my yd100 I had to jet up 4 sizes to get the poor thing to run in lower ranges or I would end up to where it would be almost jerking it's self to death as you slow down or like you said high rev and not go back to nice rolling idle. "Stock carb with red cover"

@@BuildBreakFix in my case is there an exact setup you would reccomend? Jet size? Clip setting?

@@WhiskersTheFish the problem is you jet your carb based on where you live. If your in the hills, or near the ocean, or even in dessert vs tropical jungle the same bike with the same parts will all need different jets and such because it effects the carb that much. Humidity for example vs dry air there could be a huge change in air fuel mix rates. It's why you never get a exact settings list for these kinds of things! Best start would be see what jet is in your carb. Buy a cheap set on Amazon. Go 1 size up or 2 sizes up. Put your carb clip dead center on your needle. Turn idle screw in all the way. Till it stops lightly! Turn it out 3 full turns. That would most likely be the best starting for jetting. Just by sound the motors makes. Educated guessing! Then fine tune it after it warms up fully! If the motor is cold you will end up with lean settings after it warms up if you try to fine tune the idle.

Thanks for the comment. I believe the problem you have is an air leak somewhere on your bike, probably near the carb or intake manifold. When this happens the engine will have more air than it needs causing it to rev. when the leak temporarily closes, the engine will try to die or sputter for a while. Since the day I got my bike I have had an air leak where the carb connects to the intake manifold. That is the most common place for an air leak to be .I still have not completely sealed mine yet, mine is about 80% fixed so it's ridable but not perfect. You should take some WD40 and spray where the carb connects onto the intake manifold when the engine is running. If the bike revs up high or tries to die right after you spray than you have an air leak there. If you are buying the F2 thrust pipe and racing head cylinder be read to tune your carb a lot. You must buy carburetor jets for your bike because it will need a good tune. There are many tutorials online and if you want you can keep replying to this comment if you want me to help you. Before even putting on the exhaust or cylinder head you need to seal the air leak or problem you have first. If you put the exhaust and head on before sealing the problem them you will have a hell of a hard time trying to figure out why your bike does not run even though it's tuned well. I found this out the hard way and I had to take off my thruster to try to fix the leak I currently have. I am currently replying from Pompano Florida as I'm on vacation. When I get back home I will try to fix my bike and have another video come out soon. I know I have not posted for a while but I've been busy recently. Look forward to more videos and good luck on your bike. Reply to this for any updates you have or if you need more help.

By the way, with a good tune on my bike and the thruster I was able to get my bike up to 41 mph! It was very scary going 41 on a bicycle but I was not even at full throttle and I'm sure I could have gone 45 if I was. I think when my bike was tuned like that it was perfect but again it had an air leak which caused bad idle and that lead me to believe it was tuned wrong so everything went to hell after that. Make sure to finish things before starting something new, it'll save you in the long run.

@@WhiskersTheFish Great advice dude. I really appreciate the effort that you put in, and this should fix my problem. I'll work on it today and see if it gets fixed. Thanks !

@@WhiskersTheFish Hey dude i've found a solution to it. There's some little lines for where the carb connects to the pipe that goes to the engine, and i've had to push it more towards it so that there is a complete seal around it. To make sure it was air-tight i used some electrical tape like another video suggested. I'm not sure if the vibrations will set it to where it was before but it's raining right now so i can't test it.

@@acunit1639 I tried the same thing in my bike. It not work so well and I’m thinking of using a thin rubber tube and two hose clamps to completely seal it. I’ll try when I’m back in Illinois.

They are both recycling and garbage bins. For example I have a compost bin, garbage bin, and a recycle bin. The compost and recycle you might have to pay for from the city. I know you have too for the compost for sure. I’m not sure of the recycle though.

Before you change the Jets try the way I told you drop the idle pin down, and the eclipse to the first notch and put some hoes in that plastic where the carburetor is at the black that looks like punisher face, that should make your bike run better smoother

You mean put the clip on the lowest slot and put the idle down? the lowest slot for the clip is richer which means it will 4 stroke like crazy, unless you mean the leanest which is the highest.

@@motorizedbicyclerider5296 Also do you mean the turn the idle screw down?

@@WhiskersTheFish no put it on the top the highest not the lowest where do you have the clip at right now second

@@WhiskersTheFish yes I could download a video real quick if you want

tiny metallic balls ? Where do we see these? They are created with each detonation too?

I use a GoPro hero 7 white for action stuff like when I’m riding motorbike. I also use Canon power shot sx740hs to film everything else.

@@WhiskersTheFish noice thanks! I have the 7 silver

No, you can buy it online for about $40-$60.

If your saying is it louder than stock exhaust without baffle cap then yes. It’s much louder than that. About 5 inches away from exhaust I measured about 110dB which is enough to damage your ears if you were ever to put your ear up to the pipe. You can get a cheap muffler for this pipe though that makes it super quiet and does not slow performance.

I'd just ditch those bars entirely.. not enough real estate on them for all his gear. Cant even fit a right side mirror on them. Get those bars that come with Cruiser bikes theyre like his hes using now but extend out towards him giving him like a foot of more space on the bars and he cant still keep those grip shifters.

and Red beards Garage, carsandcamerasm and Motored Life. I learned a lot about what should be on what motors and what mods to do with certain upgrades. Great channels.

In America it’s a 66cc but in some European countries it’s considered 80cc for some reason. About 2.8hp.

@@WhiskersTheFish another question do you think the f2 thruster exhaust would fit on a 49cc 2 stroke motors

You would have to look and measure the exhaust port on your engine. Mine was a 40mm so the f2 thruster fit fine but yours might be a 30mm and I don’t think the thruster is sold in 30mm.measure from the center or one bolt hole to the other bolt hole half.

@@WhiskersTheFish thanks man

His feet definitely are that hes wearing running shoes out in 30- F temps when he should be wearing insulated boots.

@@ChristopherJones16 lol, this is true. I was wearing two pairs of socks though. The air still kinda flows in. It was very cold that day.
