This is the new water-cooled Zenoah 29cc top end kit. This kit includes all needed to convert your existing 260 or 231 into a 29cc.

Included: Champion Spark plug, cooling cap w/ fittings, water-cooled 29cc jug with cap installed, piston, ring, wrist pin w bearing and clips (2), base gasket.

(Note: Kit is completely stock. Like all other water-cooled Zenoah's, I recommend turning the piston down to avoid heat and seizure. Let me know if you need this done at the time of the purchase and I will take care of it "No Charge"

LOOK AT THE LAST PICTURE this kit is useable but is missing a peice from the cylinder skirt.
