89mm + size for 440 rebuilds???

[Steven]

I scorched my sleeve on my 440.

I need to bore about .010 to get the scuff out and I need a new piston to match.

Who makes over size 89mm pistons for 440 rebuilds? I called wiseco and they do not.

Do have to get a new sleeve/piston combo for the rebuild or is there a piston maker who make plus size 89mm pistons for our bikes?

Thanks, Steve.

I don't think they make over 89 piston.

I know some 440 kits are only 88.5 and you can buy a 89 piston. If not you may have to get a new sleeve.

pro-x might have it, they specialize in aftermarket over bores, it's a japanes piston also.

.5 mm will give you about .020".
