G'day, yep it's time for a new crank seeing as though mine didn't like top gear down main straight!!,
Does anyone have a very good one for sale??

Mate don`t risk a second hand crank . You can get a new one for $700 and you know it`s right . A few people including me have bought a said GOOD Cranks only to start bike and find out it is not a good crank That centre crank bearing seal.

I agree.

If you're going to do a bottom end rebuild - all that work, spend the extra $$$ on a brand new crank.
