RE: bike reves up when pull in on clutch

Does the engine ever idle normally? How about when the trans is in neutral? Is the choke sticking on? Throttle cables free play OK and normal throttle operation?

RE: bike reves up when pull in on clutch

it idles somewhat normal when first started throttle cables do have a lot of play and not sure about choke sticking. Could this be clutch related.

I don't think it's clutch-related.
More likely your choke cable is sticking, or throttle cables need adjusting - there are two, one pulls, one pushes (sort of) maybe there's an adjustment problem, ond one is too tight (or the other's too loose ) ?

Possibly frayed cables or the twist grip sticking. Make sure that the throttle "snaps" back to its home position every time you let go of the grip. The cables may also be binding due to them being directed incorrectly. Make sure the tank isn't binding on them & they are not kinked in any way.

I agree that it may be the throttle cables. With the bike off, twist the throttle and let it go . You should hear the stop making contact.

If the cables are not sticking you may have a vacuume leak or a torn carb diafram.

A fairly obvious thought mate ...
Because the cables are push pull... try pushing the throttle closed to see if she slows down ...
If that does nothing ... disconnect the choke cable to make sure its off ...

As far as a vacume leak goes ... even with the clutch in or out ...it would idle very fast , depending on the leak size ..
I think that if the engine speed changes for any reason while altering the clutch position while stand still in gear .. you have a clutch drag issue to look at ...

As mentioned though, the cables are the first place to start in either case ..
