We have bored cylinder,shaved head, carb, reed block. we started with 120 psi in cylinder and ended up with170 psi after break-in. the Lt80 runs great. With the 170 psi in the cylinder we were looking for a big time blow out, if you know what I mean. The boy runs this machine hard and so far the Wesco 2mm over bore has worked great.
Easy bolt on solution. I was able to tear down the ATV and put it back together with this kit in under 2hrs. Started right up after completion! So far so good!
