Went to investigate what I thought might have been a hot seizure some weeks back - I put it in neutral and coasted for a few hundred yards and it came back to life fine when I put it in gear and I just carried on and have been riding it since.
But obviously it was a seizure in the making from the gudgeon pin retaining clip breaking. Classic occurance, that I had yet to experience until this point.  ____________________ CBT: 12/06/10, Theory: 22/09/10, Module 1: 09/11/10, Module 2: 19/01/11

Almot piston only 4k miles old. Used the gudeon and clips that came with it. I had to put this new one in as the old piston had a piston ring retaining pin recess into the piston allowing a ring to turn and get caught up in the exhaust port- thankfully little damage from that too.
Barrel is gouged but thankfully mostly only below the side/exhange port which is good. Might put another new piston in again. But cut the clip ends shorter to reduce likelihood of fatigue on the bend allowing the end to flex off. It's not rare for this to happen, i'm just disapointed. These sort of set backs continually occur, as one might expect with a selection of older motorcycles. ____________________ CBT: 12/06/10, Theory: 22/09/10, Module 1: 09/11/10, Module 2: 19/01/11
