Hi everyone, i've just seized my Yamaha blaster engine as the piston skirt shattered due to piston slap, i've just gauged up the barrel to find its 0.23 mm over the standard bore size, i was just wondering if anyone could tell me what over sized piston to order? Im rubbish with this type of thing and don't understand clearances and stuff i do know the clearance should be 0.02, i would much appreciate if someone could help me out? many thanks Cody.

Well you've got the result and cause out of the way... look at the next size bore or polish the bore if you can get away with it

also, post an intro in the newbies section, unlikely you will get much response as a 'randomer' on the board, just a few sentences about you, your bikes, what sort of things you do, e.t.c
