i did a compression test on my mxz 700 it has about 2200 miles on it and it tested at 130 lbs. is that good or bad? just wondein if anyone else had any numbers on this? and if so can i boost compression by changin gaskets to thinner ones or what are other ways to accomplish this. the last thing is how much can i safely raise the compression to without having to worry about losin the bottom end of the motor? i use the sled for trail ridin not drag racin or anything.
