I'm rebuilding my 95 kdx. Broke open the top end and I can't figure out what piston this is. Its a aftermarket piston of some sort. Does anybody have any idea what piston this is?Image

I'm pretty sure it's a Wiseco with the old part number. Does is have a 'W' on the underside?

Looks like maybe it's a 68.0mm: http://www.powersportsnetwork.com/enthu ... egoryCode=

(Scroll down to see Item Code 711P8.)

Yessir, Wiseco, 2mm oversize.
711 is model # of the piston.
P8 is "8th oversize" in Wiseco, which is max oversize of the stock 66mm bore.

New # is 711M06800. Same part, new name.

Thanks everyone that responded. Ordered a replacement wiseco 68mm piston set. Still waiting for my frame and swing arm to get back from the powder coating shop. :boogie:
