I just did a compression test on my 84 and it showed 148 psi both cylinders. Is this right or do you think it has had some performance work done to her? Also what length are the tracks on these machines, 121 inch?
148 is up there and it may have had some work done on it. Gauges can also vary so unless you are sure your gauge is right it is hard to tell. They should be around 130 to 140 depending on how fresh they are. The tracks are standard 15 X 121 with 2.5" pitch.
