So, I just finished my 1000 mile break in on my M2. When the bike is at idle, without me pulling in the clutch lever it sounds like my clutch plates are rattling. I haven't adjusted my clutch yet, but I can tell it needs it, slight grind into first gear.

Should I be able to hear my clutch plates? Is this just going to go away when I adjust my clutch?

Any ideas anyone?

Chris

When you say "at idle, without me pulling in the clutch lever" I would assume it's in neutral. I would suspect a little timing chain noise not the clutch plates. When in neutral with the lever out the clutch plates are pressed against each other. There's now way they could be rattleing. Sounds like time to get to know your service department or grab the FSM and adjust the primary chain.

Sick,
What you are hearing is probably, as Jst meant to say and alluded to later, your primary chain. The clutch is a wet clutch. If you can here it rattle, especially when engaged (lever extended), that would be really really bad. ;) When you adjust your primary chain, be sure to do so at its tightest position.

Primary Chain,

Just did mine once again at 22000km. I usually adjust the chain whenever I hear it being louder or when I change the engine oil and primary case oil at 5000km.

I have also heard form a service technician that a loose chanin will cause hard shifting.

Almost at the end of the adjusting screw as well.

I guess once I am at the end of the adjusting screw I replace the primary chain adjuster????

Those noises are unique to our archaic valvetrain and primary drive systems but sound soooooo goooood!!!!

OK, sounds good, but why would the primary chain stop making noise when I pull in the clutch? Does the primary chain stop spinning when the clutch is engage?

Love my Buell. A while back I asked about wheelies. Yup it pulls wheelies. Not as stable in the air as my last bike. Think I'm going to make a steering dampner.

At 500 miles I did my service and also rotated my bars forward a small amount. Much better. Like a bit of lean when I ride.

The chain's loading changes when the clutch is engaged thus effecting its natural frequency of vibration.

No, clutch disengagement (pulling lever in) does not stop the chain from spinning. It can stop the transmission mainshaft and output clutch plates from spinning though. You oughta get yourself a service manual. All will be revealed. Even when you aren't needing it for maintenance or repair work, it makes a great bathroom book. LOL

BTW, The PDF version of the '96/'97 S1 Lightning Service Manual is now online in the Knowledge Vault. Enjoy. :)
