So yesterday I was riding, not too hard or anything and the banshee died. No weird noises or anything, it just bogged down when I got into some sand. I kicked it a few times to start it back up and then it locked. I got it back home and drained the oil then took off the right side case to check if anything was stuck in there. Everything looked fine from what I could tell so I just sprayed some WD-40 on the gears and they started being able to turn. I put the case back on to test and then it locked up again after it was able to turn one time. What could this be?
