IN AN EARLYER POST I ASK ABOUT THE compression ON A 1997 XLT AND EVERYONE SAID 120-125lbs,I have 75-90lbs, and I CHECKED MY BOTHER'S 96XCR 600SP AND HIS READ ONLY 90LBS IN EACH CYL. AND HIS RUNS FINE.
WHAT SHOULD IT BE?
My 99 XLT's started over 140 new and then went to 120-125.. Dealer told me they will run as low as 70 but you start losing a considerable amount of power.. I would say if it is still running just keep going until you notice plugs begin fouling and lose of power.. Keep in mind your sled is on the edge of a rebuild below 110 psi and/or meltdown.. I think it is more important that your cylinders stay within 5 lbs of each other..
You need to rebuild,15 pounds is too much in the difference.you might be able to get away with just a set of rings if your lucky.not a big deal.your brothers is fine because all three cilenders are the same.but he would find a big diference in power with new rings two.
