Hey guys, new to the forum, but pulled up a lot of great info before getting the 4-wheeler, and some really great guys and info on here! Glad to be a part of it, and hoping I can get some help. I did some trading for a 94TRX 300FW that was in really good shape, but needed some love. So, over the last few days, I've changed out front and rear case oil, oil and filter, and some other nit pick stuff. When I got it, it didn't smoke a bit, which for it's age was impressive and a good sign of proper maintenance. WRONG! There wasn't a half quart of oil in it and was like sludge. After changing it and the filter, it smokes like a freight train! Used Honda oil and filter from the dealer here in town, and even took the filter cover off to make sure I didn't install it backwards, so it's installed correctly. My guess is I'm hosed and have to fork out a crap load for an upper build and valve job! Any input, suggestions? I read another guy had the same issue, and everyone said that it was weird and almost unheard of, but here's another case of the same issue.
