Vibration Micargi

[butre]

no need to do anything with that frame post since with the engine mounts there is a solid triangle.
Just get the wrist pin

what makes a triangle strong is that there are 3 solidly mounted points. this only has 2

i read all of your ideas..thanks! Ok im buyin the wrist pin..if it still vibrates a lot I will have the stem welded. thanks for all of the help...my next build is the same bike with a 125cc

This may be a new forum topic but what kind of engine do you have in mind? Centrifugal clutch? What kind of gearing scheme do you have in mind?

dont. theyre very heavy, and very wide. you would need a super wide crankset to clear....feasible, but very very difficult.

erm...go search the thread "my first custom build", look at the dates...and its only just starting to near completion. mind you, he has done it properly from the ground up, cnc jackshaft, brackets etc... looks very nice

pffft, ill just link to it...

you can use this one which has a larger diameter hole in it:

If that doesn't correct the problem enough then you can
1) buy a Jaguar CDI
2) drill balancing holes in the crank flywheels

There is one simple test for your motor mount.
Grab your top bar with one hand, the your piston head with the other.
Now try AS HARD AS YOU CAN to move your engine back and forth.

If it moves AT ALL, that's your vibration.
