I got a '01 YZ426F a couple weeks ago, it ran well until the 2nd day out riding I was about to run out of gas so I was trying to get home when it felt like the bike locked up.. I feared the worst and thought it was seized, but when I went to take the tank off, I realized it was infact empty. So I pulled the right side cover & valve cover and all looked ok.. I changed the oil filter and there were aluminum particles in there. I looked around online and found out that is pretty normal for these. I was able to back the bike up a little bit & the engine turned freely and seemed to be fine. I figured I had just "vapor locked" the engine. I decided to do an oil change, when I changed the oil filter there were aluminum particles in there. I looked around online and found out that is pretty normal for these. so I put a new oil filter in and 48 fl oz of Rotella T then decided to go riding.. I started it up and made it about 1/2 mile into a field then it just died/tied up and wouldn't unlock from rolling backwards. I started working on it today and when I drained the oil 72 fl oz came out!! I had drained the oil out of the holding tank but not the bottom end before adding the new oil.. Now I'm trying to figure out what the damage to the engine is. What would be the most likely failures from having 24 fl oz of extra oil in the engine? It seems like the case would be quite full.. I put it in gear to try to rock it to see if it'd break free, and 1st, 2nd, 3rd work fine (rolls a couple inches then locks up) but 4th & 5th act like neutral.. It seems unlikely that the trans would fail at the same time as I believe this failure is due to the extra oil and I don't see how that would mess up the trans, more than likely the rod IMO.. What's the best way to trouble shoot this further? Any ideas?? Also when I pulled the plug it was dry, so the oil didn't make it past the rings Thanks for any help you can provide!!
