Had a small issue, sent them what they requested and they took care of it quickly. Thanks ZOOM ZOOM PARTS!

I purchased this top end kit for my Daughter’s Yamaha PW 80. The piston rings, cylinder, and head was ok quality. The piston itself was made out of cheap aluminum and of course everyone know heat causes it to expand. After the engine heats up to 180 degrees it would bog the engine down and shut off. So I was very lucky to have a barely used engine that hardly had any scaring and reused the original piston. Also the head bolts were weak. If this kit had quality head bolts and a better quality piston it would be the best.

Decent, especially for the price. Don't use the spark plug, it will literally melt after 5 minutes. I rebuilt a basket case so I'm not sure how much power this bike should have, but after installing this the bike pulls and hits powerband with me on it. I'm 200lbs

Studs and nuts were cheap. Had one stud strip out, but other than that, the kit worked perfectly.

The media could not be loaded.  Worked as it should ! Everything fit well and bike runs great !

Everything came in one peace , packaged nicely, and fitted properly for my 2002 Yamaha pw80 dirt bike. Before the bike literally had no compression due to burnt piston, and cylinder walls.But with this it runs like new!However I must say the top header looked a bit iffy from the machining process, but runs fantastically with proper instillation!Over all a great value for all the items you get in this package.

This is a great product.i broke one of the rings and they sent me another pair. Customer service is excellent. I used this top end for my son's Yamaha pw 80.
