Before loading my bike for its first race I tried to start it and guess what? All it would do is backfire and not start(broken woodruff key). I posted a few days ago about having over 400 miles on my 450 and no problems of any kind. I knew if I did that,and still had no probs I never would. Well so much for being bold. The good part is my dealer had a key and lapped the S.O.B and got it going for this weekend. They had retorqued the rotor nut when I got the bike back in Jan. Sorry for the bad news but this is more than a torque(rotor nut), jetting issue. I'll post Sunday night if it holds up or not.
