[Little Homie]

I need advice on the best brand and weight of oil for my 1986 450 Rebel. Thanks, Jason

I use Honda GN4 in mine. Its made for motorcycle engines, and thats what the manual recommends in my '07 250

What ever you get, make sure its a motorcycle oil, regular oil is bad for the clutches. I use lucas oil full synth. 20w 50 in my roadstar and in the wifes vstar.
