I have a 2014 WR450, I have noticed that it wants to go right, not exactly pulling, just sort of wants to go that way. I have messed with the bar alignment, changed the fork oil, re-packed the stem bearings, changed the front wheel bearing, changed the front tire and checked rear wheel alignment. I do have Flexx bars on it so I replaced the bushings on those. So I am down to two possibilities at this point. The bars don't appear to be bent, but the right side is about 3/4" taller than the left, but since they move and the concrete on my garage floor is pretty rough I am not real confident about the measurement. The other thought I have is that the inner cartridge seal on the right fork may be going. When I changed the oil it took quite a bit to get all the air out of it. Before I shell out the money for new bars and /or tear the forks apart again, anyone have any ideas what else it could be?
