I have an 07 YZ450f and it will shift into neutral in between any gear. I have had this problem ever since I split the cases about a year ago and it never really bothers me until I hit the track and almost kill myself because I bump it between gears like 2nd and 3rd. I have heard of this happening on these bikes but what ive read seems like it only happens from dirty oil or poor technique. But I'm guessing this is not a normal thing. My shifter is tight, oil is new, and I can go out and ride and shift from any gear to what seems like neutral. If I am between gears how can I correct this. Could I have screwed something up when I put the cases back together. Anything I can do to fix this as racing season is upon us and I dont want to case another jump because I hit neutral on a jump. Please help!
