	98 XLT motor w/8600 miles 3 pull compression test results PTO 120 Middle 130 MAG 125 Pulled Carbs to inspect pistons Viewing intake carb side MAG looks clean no real build up or scuffs Middle same nothing really PTO slight scuffs middle of piston up to top looks to follow pattern of port just to the inside of port and in the middle where there is a land or bridge area for the cylinder? Question is this normal wear? Or should I be concerned? I am trying to get a picture to post but tough to do! Should I just leave it knowing compression is OK? Rating: 0 Quick Edit Edit Topic

	Sounds like noemal wear with that kind of mileage. I would eun it for this year and do a rebuild in the off season if you plan on keeping sled. '01 XCR 800 '00 Indy Triumph TRIPLES RULE!! TWINS HAVE NO BALLS!! Rating: 0 Quick Edit Full Edit

	What he said ^^ If its never been opened up, I think those numbers sound pretty good considering the mileage Have you looked at the exhaust side of the pistons? If you're not livin on the edge, Then you're takin' up space! Rating: 0 Quick Edit Full Edit

	8600 miles is getting up there for that triple motor and pistons/rings. To do a top end on that sled, is clearly a 6 pack of Heinekens, 3 pistons/rings, top end gasket kit, and Antifreeze, or about 1 hour!!!!

	Run your fingernail across the scoring.. If you can feel the ridges, you may want to consider replacing that piston before you have to replace the whole jug. 95 - Storm 800 - Modded - AKA: FrankenStorm - Totalled near 100mph at Tug Hill! 96 - XLT/SP with Storm 800 trip/trip and now EFI - FrankenStorm II lives... 95 - RXL -- Sale Pending -- 05 - Edge 800 long track - Stayin' stock for now.. --------------------------------------------- It made me more compassionate, more empathetic, more nurturing...
