Purchased and rebuilt a 1997 Honda xr250r bike. I don't have the owners manual. What weight of oil does it require and how much? Thanks!

Again, we have an old school air cooled engine here....

I recommend anything from Maxima. It has the best additive package in the industry! Probably for an old banger like that, the relatively inexpensive Maxima Premium will be just fine.
