KLX piston

[gtmpaul]

Hi all
Ive finally got round to taking the head and cylinder off the KLX, hope to sort out the smoking problem.
It's running a +20 piston already and the bore is well shagged.
Has anyone used another of the Kawasaki range pistons as some of the time part numbers match up with Z1000's, just thought that it may be OK to run another part number, here in the UK the only one available is +20.

Paul I just checked the fiche for the early twinshock KLX250 and in the US they list the following genuine replacements

PISTON,0.040 O/S - part# 13027-1005

RING SET,0.040"O/S - part# 13024-5008

maybe a dealer could try to order this or you could try US dealers.
