took our 250ex out for a test ride (been sitting for a month) before heading to coal creek in TN. Heard a squeeling that seemed like it was comiong from the final gear. Checked it and it was very hot. Checked gear oil, maybe a little low but still got a little flow fronm check bolt. Let it sit and ran it again no noise and didn't get hot, but reverse not working. Any thoughts? Anyone been to Coal Creek?
