    Low Compression

    I have a 2000 OX66 and the highest compression on any cylinder is 95, with all others within 5% of each other....Should I be worried???

    So the lowest cylinder was around 90. Sounds a little low but not too bad. If this were mine I would run some engine tuner through it and shock treatment with ring free run it a while and recheck it. As long as they a even its probably OK

    maybe but your numbers dont sound very low to me. The only way to fix it is to overhaul it. Try the tuner and the ringfree shock like I said and see if that helps it.

    I would like to see the difference in the numbers when you hold the throttle open. I have never found it to make much difference.
