My 08 ltr clutch just started slipping right after i changed oil. i put Motul 10w-40 in it. my local dealer said its a very good oil for the suzuki's. well right after i changed the oil took it for a ride and just a little bit of throttle its fine but when i get on it it slips. i tore apart the clutch and the plates were not burnt or warped so i oiled up all the plates and put it back together. took for another ride and it slips still. im really stumped on this because i have never had this happen to any of my quads. did anyone have this problem. please help
