Hi all, I have purchased a 92 (i think) big bear 350, that wasn't running, i have just got it running and now in the process of seeing what else is needed to keep it running and serving it. I was checking the rear diff oil and opened the filler plug and water came out. The question is how did water get in there without going back out the same way it got in?.
So I am going to drain it and put in new diff oil, what type of diff oil is best (viscosity) and how much is need for it? I'll do the front diff at the same time as the bike doesn't look like it has been maintained well.
