RE: Honda Foreman oil change
I forget on turning the service light off... I think you press and hold the odo and reset buttons? Anyway it is in the owners manual.
Royal Purple 75W90 would be fine. There is a drain on the underside of both difs.
On the front dif, there's the big cap on the side. Fill the gear oil up to the bottom of that hole. On the rear axle, you pull that oil check bolt, and the cap on the top. Add oil through the hole on the top until it begins to come out of the check hole.
Also, don't forget to check the valves.
