O.K., I need some more advise. In 1993 on my YZ250, I managed to come up short on a double - no crash, but front end down first - sort of off angle as well. This tweaked my front end, and I was never able to get the bars and front forks/tires re-aligned again. I was always steering slightly to the left or right, to keep the front straight - this is a very irritating thing because it affects your ablilty to turn accurately and quickly. I put new bars on, that was not the problem. I had the forks and everything else checked and nothing was bent or distorted. I tried every possible method of disassembly and reassembly - in the end, once I was back on the track the front end was always back off center by the end of the day. I put the forks in the clamps first, then tightened the pinch bols, then the crown nut, then the wheel/axle, you name it, I tried it. The upper and lower clamps are not keyed together on Yamaha's. Are they on any other mx'ers? When the crown nut is tightened it is supposed to be 125 ft lbs or so - I go by spec and use the right tool with the right angle. Am I making this nut too tight? If I leave it looser than spec would the front end be able to "spring back" to center again? Heres's the punch line - this very same thing I have done on my 426 and it has REALLY, REALLY, REALLY got me P.O.'d - to say the least. O.K. - I need help on this guys!!!!!!!
