I just changed the tran oil, its 650cm or w,e the messurement is. I beielve its like 80/85, but then someone sayed 10w 30 or 40,,,, just at the bike store get 2stroke trans oil, all the same crap. Search online for a manual.

dunno about the forks but I know my bike takes 80weight gear oil (such as Bel-Ray Gearsaver) OR 10w30 MOTORCYCLE engine oil. I use Bel-Ray and it seems to work great... it didn't shift as smooth with 10w30 Yamalube. I have a 2002 model and it takes 650cc (650ml). It'll say right on the side of the casing how much oil the tranny takes.
