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

Great product for the price

Installed four-ish months ago and rode all summer with zero issues. Seem to be good quality and the cost is much cheaper than OEM parts.
