i have a raptor 660 2002 and i just got it and was wondering what weight oil to run in it...a prefer amsoil...i live in wisconsin and wont ride to much in the winter

 

Heres my first choice, I run this in my R6 and in the tranny of the shee.
0w40

Close second would be this, if I ever take the bike to the track ill run this. The 0w40 makes starting a little easier though.

Both are wet clutch safe and excellent oils.

 

well i have an 05 but it shouldnt be much of a difference...you should be usin 20w 40 its synthetic too (well mine is) yeah not too thick but thats what it should be ran at ....0w 40 is that kid crazy thats *****in thick dude thats more than diesel...btw you know that when you use amsoil your not supposed to use anything else from then on??

 

Yeah I have run it for the last two years with no problems
