Can’t beat it

I put this top end on, started first crank, I rode the heck out of it the first ride. Runs great. Literally can’t beat the price . If it blows up in 6 months I would still be happy , an order another kit

Fits my bike

Solid top end honestly. Gap the rings properly and you will have no issues. For the money it’s fine.

ok

got it in today, expecting somthing to be broken or missing but nope, came well packaged and with all parts as described, comparing it to the oem cylinder and other parts can hardly tell the difference, just the head is different color

WORKS GREAT

easy install with the help of some YouTube videos this kit does not come with instructions... I read a lot of reviews about crappy gaskets but I coated the block to jug gasket with some gasket sealer and I haven’t had any problems... my kids have ran about 10 or 15 tanks of gas through this machine and it runs perfectly with no smoke .... I AM VERY PLEASED WITH THIS PRODUCT

Great cheap fix

It’s not oem, but works fine. Everything needed to replace a top end.
