Hi folks,

got a wrirring primary seems to stop when you pull the clutch in. I plan to check the compensator on the weekend (and use the right loctite, my error) for the correct torque, as well as the compensator spring but just want to know if there’s anything else to look out for?

I’ve heard the inner primary bearing will also make a wrirring noise but I’m unsure on how to correctly diagnose or identify this?

as well as that I just want to know what else to look out for when I’m in there..

 

Could be one of several sources but if the noise stops when the clutch lever is pulled in, very likely the inner primary bearing is the problem.

 

and can I ask, how urgent of a repair is this? Can I leave it till winter, or is that risky

 

Some of the years back then for the issue with the inner primary bearing were alignment issues brought on by the mothership failing to dowel the cover.

However, the bearing could just be worn by now.

Google search will pin point it. If you have had it apart, maybe going back together affected alignment. With out dowels, covers need support as you snug up and then torque the pattern properly.

I would do it sooner the better, but probably not going to fail tomorrow

Ive used sockets abd thread rod to press in and out. Plus some kind of plate

I would consider tranny shifter seal when off, or at least inspect it. Everything might be 20 years old. Jack shaft seal too.

 

This only became a problem on the 6 speeds.. The 5 speed tranny did not have this issue..

It could be the inner primary bearing but I've also managed to blow the mainshaft bearing in the trap door.. Makes the same noise. Also the inner primary bearing race can walk into the main drive gear. Another is issue can be the needle bearings inside the main drive gear walk.

It needs to be fixed..

 

To diagnose a failed inner primary bearing:

Noise is present when transmission is in neutral.

Pull in clutch lever, the noise may stop.

Drop into gear, the noise will definetly stop.

 

im going to have to say the. It’s unlikely to be the IPB as the noise is there in gear or without, again it’s very subtle. This leans me to believe it’s a too tight chain of or comp nut

 

In gear with the bike stopped?

If so could be a loose comp nut..

 

i think it must be, I torqued it a few weeks ago but admittedly didn’t have the step tool and used a rag, and also used blue loctite, now got the locking tool and the red loctite so will open her up on Sunday nd see
