I bought a 96 MXZ 670 about a month ago and when I checked the compression both cylinders had 165psi.
This last week-end I bought my son a 98 MXZ 670 and it has 145psi per cylinder. It had the top end rebuilt 250 miles ago and runs great. Why the difference? The 96 runs stronger and they are set up the same. Maybe the 96 has had the head shaved? I dunno......
Also both these sleds factory exhaust rattles are really annoying. Will it hurt to remove that alluminum cover on the pipe?
