I am planning on getting my squish band altered on my 98 cr250. In doing so it was recommended to do a compression test so I did and got a reading of 240#. I thought maybe my gauge was whacked so I invested in a good MAC tools guage and got the same reading. This seems pretty high to me. The procedure I used to test was warmed up engine, took off gas tank, held throttle wide open and kicked until the needle quit moving - about 15 kicks. My bike has an oem replacement cylinder, wiseco piston and what I assume is a stock head. I run the premium pump gas and have never noticed any detonation. Piston and cylinder have about 30 hours of operation. Anybody know if 240# compression is normal or if I did the test wrong?
