1st race on my new WR 450. Rode to the line, e-buttoned it 5 minutes to go, kicked it at the 2 minute warning-started right up both times.Scootched up near the Gas Cap and watched the banner. Banner drops, hit the button 2 times, NOTHING! Kicked it and it fired, now looking at 70 or so riders 300 yards out and a buch of dust! DAMN! Mission Yamaha requested I bring it in to examine the "fragged" switch. The flange at the switch base on the grey button broke off, Warranty replacement-NO PROBLEM! Keep in mind, this is the same Dealer that lapped the Flywheel and Crank for me before I took delivery. About 100 Miles on it and NOT A SINGLE PROBLEM (other than the switch). Consider carefully when you buy your new toy-PRICE IS NOT EVERYTHING! The deal I got from Mission Yamaha was the best in So. Calif. and so far, they support the product they sold. I highly recommend them!
