Hey fellow WR450 owners, my first posting ever in a discussion forum was about my starter chaos on my new bike. Don't know or understand all the rules, but I'll figure it out!! The starter problem is real. Bike worked perfect till I let a friend ride it. He stopped, went to start it and the starter would not engage. When every conceivable thing was tried to get it started, I new it was not something simple! It sits at the dealer waiting for a new flywheel nut and woodruff key. So hey, is there a flaw in the starting mechanism that won't take the kick-back if you happen to have the throttle cracked a little when you start it? Or did I just get the bike the production worker forgot to torque the flywheel nut? Time will tell, but just trying to see if anyone else has experienced a similar problem! I had 96 awesome miles on it b-4 it broke....can't wait for it to be fixed. Hope this was just a fluke. Still had throttle stop in, but its coming out as soon as I get it back.
