Hola everyone

I'm looking a bit of advice from anyone who own's an early big bang R1 as I have a 2009 Yamaha R1 and have been having a bit of trouble with the clutch lately,

It's very 'judery' ( Technical terms ) down low in the rpm 1-3 rpm
And when pulling away (especially when cold) it sounds like the clutch plates are grinding together it does lessen when warm but is still there and is random there is no main cause.

I have trolled the internet and couldn't find anything so before I go to the stealers looking some advise or experience

Thanks

Have you a tight spot or seized link on your chain.

No chain is free with no tight spots or seized links

Its cleaned with petrol and greased every week mileage dependant

warped plates?

Is the rear sprocket hanger bearing OK?

Possible but it changes gear fine very positive and smooth

You mean movement in the rear sprocket ??

wouldn't make much if any difference once you are moving.
