CDHPOWER 2 Stroke Gas Engine Motor Kit Piston Set of 66cc/80cc - for Longer Connecting Rod Crank Assemblies - 80cc/66cc Gas Motorized Bicycle

Good quality in perfect shape. Replaced my stock long rod high hole pk80 piston for a G4 cylinder. Fair price.

Piston ring broke after 8 months due to some harsh riding and experimental procedures (july-march) but 2 strokes are gonna break eventually. Great product along with the cdh black cylinder body.

Worked great. It was well pavkaged and arrived in perfect condition. The only thing I didn't care for was that the rings are already installed and I needed to cut a window so there was a pretty high risk of breaking one if taking them off and putting them back on. I just wanted to ensure there wouldn't be any flakes of aluminum caught up under a ring. I was able to just wrap the top part of the piston in masking tape and it kept it clean so no big deal. Also I think the price is a bit too much considering I can get a really nice cylinder for almost the same price. All in all it wasn't a horrible deal, and I got exactly what I ordered, on time. I wouldn't even take a whole star for those minor gripes, maybe 4 and a half would be a fair rating.

Was very confident ordering this because I wouldn’t want it to fit in when I got to chowder is CDH They gave a better price description how to describe this product so I know I was getting the right one when I ordered it glass one just said piston for 80 mL and it wasn’t the right piston I was very confident when I ordered this piston that was it if it very easy to install had no problems runs great

No good

Well so far it doing great not bad to say other then the fact that I honesty think that you should also includa wristpin barring as well

Nice product

It's a perfect fit for the pk80 or ld90 47 or 48 all the same
