hey guys. new to the site. i have a 2003 raptor 660. over the summer i replaced the clutch battery rear bearings chain sprockets and rear tires. since then ive rode it probably 2 hours and it rode great. then this past weekend i rode it about 2 hours and its was acting up. when i shut it off and turned it back on and shifted to first gear and hit the throttle it wouldnt move.it just revd up. i figured that the clutch cable was to tight and loosened it. it moves but not the way it should. 1st 2nd and 3rd gear should be lifting but its not. its just revs. could it be the clutch or the chain and sprockets? something else? any help would be great. thanks guys!

Adjusting means setting the freeplay in the cable. If the clutch continues to slip after you adjusted and you have freeplay, your clutch is probably burnt...............

If the clutch that your mechanic used was ment for the 660 then it should be a wet clutch. Should be running 10w-40 in the crank case. If you have adjusted the cable out to its maximum then you prolly burnt up the clutch when driving it and it slipping at the same time. Are you sure your not screwing the adjustment the wrong way?

The oil should be wet clutch compatible, no energy conserving additives..........

If you squeeze the lever you should be disengaging the clutch.......If you are letting the clutch go, it should be grabbing slightly after letting the lever go from all the way in..............

If I'm using Pennzoil 5W-30 Synthetic, is that a bad idea? I burned my clutch out in one ride, could that be why?

Does it say wet clutch compatible on the container.

If it has energy conserving additives, it will ruin the clutch.................

It it says JASO MA it's ok. If it's SM rated, probably not! Just about all SM rated oils have anti friction additives that are not clutch compatible.

It says resource conserving so it's probably the same thing as energy conserving. Taking it out now. I have Valvoline 10W-40. No energy/resource conserving crap on the back but it is SM rated. I'm guessing that won't work either? Are there any types of oils that I can use for the Raptor at an auto parts store? I heard Shell Rotella T.
