Big bang R1 clutch

Post by R1 Paul » 30 May 2015, 22:11

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 :lol: ) 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 :D

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

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