the bucking bar on my 66cc 2 stroke is too long, ever since i took the clutch apart to see if the pads where gone and put it back toghether i noticed it sticks out to far, about 7,8mm too much so i cant put the clutch cover on, i know a simple solution would be just to cut the bar but i wanna know wat use think first

Something must be wrong, if you do replace the bar DON'T cut yours. Get a drill bit the same size and grind it down to the length you need.

Are there 2 ball bearings inside your transmission shaft? There should only be one.
7 to 8mm is about 5/16" which is the diameter of the bearing that goes in the shaft which also, coincidentally, is the length that you say the shaft is sticking out too far.

It was working or should I say fitted together. Problem only after he took the clutch apart.
 
How bizarre!
I am a bit leery at the idea of cutting something that originally fit before the assembly was torn down and reassembled. The drill bit idea is awesome as the resulting bucking bar will be leaps and bounds better than the factory one, and the original equipment bucking bar will still be intact if needed down the road. Still, if all the ingredients of the clutch assembly have not changed, and everything was assembled to original spec, something is not right here. Metal does not grow all by itself.
I wish you the best of luck with your repair, ae86lad. Something has definitely gone screwy in there somewhere...
 
ae86lad, as mentioned, do not cut the bar. Something is weird here. Is it possible that, as GearNut suggests, you have two ball bearings in place instead of one?

Hey my bucking bar goes in all the way I think the bearing is gone. How can I fix this.
 
Hi,
Anybody knows what was the solution to the "too long bucking bar" problem?

Thanks

Probably his flower nut wasn't on as far as before, causing an unnecessary amount of clutch separation when the lever is pulled, but the too "loose" flower nut causes this by means of lengthening of the clutch push rod assembly.
Meaning that if you can separate the clutch plate from the pads by more than the minimum (about 2mm or so, just enough to not drag) when you fully actuate the cam, then your flower nut isn't screwed on far enough and you'll see more than the normal amount of bucking bar protruding from the drive sprocket.

Or sumthink :rolleyes:

I think the solution is that the guy gave up, if you took it out and put it together again it can't be too long, the bar never changed, my question is why do you ask? I think your problem isn't what you think it is.
