Nice little motor!👍
The tweaker mobile
No sir
😂
❤where to pick one up ? Nice
You are a genius mike! It amazes me how you do this! This is the most awesome crank balancing calculator I've ever seen! You truly are a blessing to everyone who is trying to do this! Thank you bro!
It can be a little tricky, sometimes shimmy a crank. First of all, you have to know where the center of your crank should be and go from there. Sometimes you have to put shim on both sides of the crank and sometimes more shim on one side of the crank than the other to get it centered correctly.
Super nice bearing to use! It make the clutch a little more quiet.And this bearing will last a long time if You keep it packed with grease!👍
Nice job!👍
i am a lil confused where are u getting the 360
aw nvm lol
@@GasBikeFanatics I'm still trying to figure out what you're referring to
Gonna rip, how are you gonna bolt the head on tho?
MAN THANKS ALOT NOW I KNOW WHAT I WAS DOING WRONG I WAS ABOUT TO BUY ANOTHER DAMN CARB
That's not from power. The seal wasn't installed right.
Who said anything about power? I know how to install seals, I've been doing them for a long time. If you can somehow install a seal incorrectly you shouldn't even be allowed to ride a bicycle.
@@MikeNBikes sorry should said pressure. Autocorrect. It's easy to you just dislodge the inner ring.
Replace the bearings and balance the crank but even just with better bearings makes a lot of difference for some reason the stock bearings I had were shielded on both sides which I know is not what you want I went with skf and Dunlop bearings 🤙
Yeah sometimes when you rebuild the carb it starts pissing or leaking fuel means that fork adjustment so it engagement is quicker then stock the float arms I just did it to my bofeng carb it no longer leaks
Deck the top of the float bowl. Its responsible for most cronic leaky carbs.
I jusr uploaded a video about my rod bearing. Is that too much play? (It ran just 10 min)
I just looked at your video. That is completely normal. You should only be concerned if you're holding the crank in your hand and pull up on he conrod as you are. If you're able to pull up and down on the conrod, you have an issue. It's difficult to do in the case because naturally the crank will want to spin Question. Where exactly did you get that engine from? I need a bottom end with that crank.
@@MikeNBikes there is no up and down play. I got it from ebay. Some one told me that it has to much side to side play
@@Potato37184 Could you link me to the exact listing? Because that looks to be a good crank Do not listen to them. I promise you, all cranks have side to side play which is normal. Factor in heat tolerances as metal expands. If you had up and down play I would be concerned. Anyone who is telling you its an issue most likely has either not split a case, or handled many cranks and is giving you bad advice.
@@MikeNBikes youtube doesnt let me post links.. my comment gets deleted after i have a Link in my comment. All i can say that it is a cheap china engine
@@MikeNBikes and how much rpm can the wristpin bearing and wristpin clips hold befor blow up?
Which way does the White Float go???? theres an Obvious ribbed corner on mine.
Nope, that is just from manufacturing. The way it is placed will not affect how the float works
where should i connect the vacuum lines for this carb?
How you get bearing over
Thanks for reminding me to do an update. Stay clear of this clutch basket, it looks nice at first but it isn't. To answer your question, a 6809-ZZ bearing is pressed onto it. The bearings ID is 45mm which is slightly smaller than the baskets OD, so either they press it on with great force or they're shaved down slightly. The problem is during engagement and disengagement the basket doesn't stay "whole" stick with the normal ones
You still owe me money on your bounty on port timing. 😂
You're still unable to explain the mathematics other than repeating what you're saying as the explanation of what you're saying
Thank you.
you can fix that easy use a rubber mallet and straighten up that bolt by smacking it till it's straight
lol just easier to buy a new axle, but it was toast unfortunately
the 2 engines i bought from CMB ive got 17mm ones
I've got there straight and angle adapter from them
I bought their 48mm to "hose" flange adapters and it did not end well. Really the biggest issue was it lacks surface area for the hose to grab properly, and while it isn't a deal breaker, it does remove one more vulnerability for an air leak
I actually figured out a much much better way of starting it, which is just more beneficial for me as rather than doing a kickstart especially when it’s cold it’s easier to pull the clutch in pedal a little bit and while you’re moving, let the clutch go and once it starts, pull it back in and then you can put the kickstand down. I found this method a lot easier than having to weirdly lift it up just to start it, especially in the winter of Ohio😂 And as long as you’re moving, slow enough, you can let the clutch go and pull it back in as many times, as you want until the engine starts rather than having to lift up the bike and kickstart every time which from experience is very tiring
Whats up! ik im late but for a pedal start motor can i do the same?
It’s bad the runout is too big for ride 🤘🤘🤘
Ouch
😂 that has a very rough life! Taps song is in order lol
My float was on the bottom pf the carb
Huh?
I have a special tool made by Kevin's shop removes and helps you install them as well
Got a link ?
Bearing is in wrong..... You have them reversed. One side Open bearing goes toward the crank. *Open side* Double sealed goes on the clutch side
No, they're correct. I keep both ZZ shields on until it's time to launch, then I remove the inner. The clutch bearing was originally a ZZ. I prefer to run 2RS but I figured I'd make use out of my excess ZZ bearing stash. I pop the shields off and insert 2RS seals. What you're seeing is me not pressing in the outer bearing seal yet. Kind of like this video below. ZZ bearing but will have the shields removed and 2RS seals pressed in ua-cam.com/users/shorts8Zm-49BMeB0?si=p0F4u96NJqOeVzBT
I'm thinking if the lighter thinner crank is plenty strong enough. You're better off using a stuffed case with a lighter/thinner, balanced crank that'll spin easier- ala less rotational mass.
Hell yeah I like it
