you have to remove the lower half of the throttle housing, you'll then see where the to/from cables go into an L-bend, there is a slot in that to feed the needle into! I do not have pics, but I know the first time I did it I took the whole thing apart, then banged my head, then, saw the little slot access point
So this is a newbie question as I just bought my first bike (09' raven 6r) a couple weeks ago. Do you just lube the clutch and throttle cables or any others as well? And all that is used is synthetic oil?
