I have a 2007 crf450 that has a little over 300 hours on it. The current crank has about 120 on it, so I am planning to do a full motor rebuild next month. All original transmission. At the end of last season, I had it pop out of 3rd on me twice, never had that happen before. What should I be looking at and measuring to determine the cause ? Center shift fork? The gear itself?
