I’m looking for some advice on doing a compression test on a Honda foreman 400 1999 model, I have the compression tester gauge and I have the compression range, the Honda dealer i spoke with told me the compression should be 178-206 psi with the decompression not affected and 75-121 with the decompression affected both at 450 rpm, can any one shed any light on what exactly this means?
