I am starting to rebuild a js440. i have had the bore hommed and its lookin neat.

I measured the bore today and got just below 68.00mm. thats from the top of the head.

The smallest kit on the internet is 0.25mm oversize kit. i thought that might be to tight for it in the bore.

so how do i go about this problem do i have to get the bore bored out or buy the 0.25mm kit or is there some internet site u people know of with new standard pistons?

Help is greatly appreciated.

Thanks

Powersports plus sells standard size OE pistons, but they are $81 a piece!
