what should the compression be on a xlt 600 triple
the sled has 6000 miles on it
from the clutch side it reads 115 125 130 ball park reads

I would say around 130 would be good, 120 ok, 110 fair, and 100 needs a rebuild. Usually you don't want more than 5psi difference between the cylinders so the 115 is a little sketchy.

id say its gettin pretty close to time to do a rebuild. They should all be pretty close to each other. But if it was me id run it till it starts hard cold and warm, But the smart thing to do would rebuild now..


this is how all our sleds read..

98 xc 600- 119 pto, 120 recoil
99 xc 700-129 pto, 131 recoil
00 indy 500-95 pto, 93 recoil

Yeah, 20 off is quiet a bit. I'd say its time for a re-build, if you plan on riding a lot then this year, if not....it can wait til next.

well 1st its not a 600cc tripple.... its a 580cc tripple. and 2nd time for a rebuild in my opinion. and if you rebuild make sure to check the bottom end out. they do have problems with the bearings

Unrelated to the topic, but how do you know its the 580cc and not the 600cc? As I recall he did not specify what year the sled is.

Whoops, my bad. I didn't notice the '93 in the title. bokeson is right, it is a 580 cc

the sled is a 1994 and i did research and it is a 600cc but back to the compression question should it run on the compression given i know it should be boggy but..... how boggy would it be

as people suggestion before, rebuld it.
10 psi is about all the deiiference id want. its easier to rebuild it now and avoid an expensive fix later

Unless someone put a 600 in your sled its a 580, 93 and 94 where 580s. Just in case you decide to rebuild the top end on it, 580 and 600 have diffrent pistons, dont want you to get the wrong parts, just make sure it is a 600, they both "look" the same. The 93 and 94s bottem ends had no issues.

The 93-94 XLT's were 580's. The 95-2000 were 597's- they were all called "600's".
