After stripping a friends motor we've discoverd it's a 240cc Kawasaki conversion. The piston is 71mm (is that an oversize?) and the rings were worn so they've been binned.
It's an original piston and he needs a set of new rings...can you still get them?
Cheers Stu

71mm is standard size for the H2
Be easier to buy a Wiseco H2 piston and rings, wiseco ref no 423M07100OEM
rings are ref 2795CD which is commonly used on wiseco 71mm 2 stroke pistons
OEM Kawaski H2 stuff is rocking horse manure unless you can find rings from another piston to suit

if you do just want to go with just changing the rings and it is an oe kawasaki piston it's worth trying here : https://www.z-power.co.uk/merchantmanager/
the kawasaki pistons need repegging, but the wiseco items don't.
I've been looking for a 71mm 423M07100 wiseco piston for my big block build with no luck, although i didn't know david's brands hatch suggestion.
ended up getting a first oversize 423M07150, which is not ideal, but fine for my needs.
if you mate's does need a rebore and you get hold of a new 423M07100 kit, I'd swap it for mine, all BNIB.
any more info on the spec and how it rode would be useful as I am still at the collecting bits together stage of my build.
