Worked perfectly
I was a little skeptical of ordering this kit after watching some videos online and reading some other reviews but I could not resist the price and bought it anyway. I checked the cylinder height and it was correct and didn’t require any machining, I used all the parts and the kit including the paper gasket on the bottom of the cylinder and the O-ring was the correct size. I was very impressed with the piston rings as the second compression ring is actually a oil scraper to prevent burning oil. The stock piston comes with two standard compression rings which have failed on my bike and was smoking like a freight train. I install this kit with no problems at all and has been working perfectly would definitely recommend to a friend and buying again

drips antifreeze
I bought this cylinder, it was fine but I had a problem with antifreeze leaking through the middle of the cylinder and the head, how can I repair it?

Inexpensive motor rebuild
Cylinder looks to be seated and machined well. O-ring for the bottom of jug was to big. Installed on a 05 rhino 660

Great kit.
Perfectly fits my 2005 Yamaha raptor. It was great to be able to convert a 660r into a 686 (aka 700). The power difference is easily felt and this kit made it possible and easy.

Its junk.
If I could turn back the hands of time I would. The cylinder will move on you. Its not decked flat and it's not worth it for the price
