Posted May 30, 200816 yr Hi all, Just purchased a new Yamaha 2007 WR450F. Love the bike. Here's the problem. Even after keeping the battery on a battery tender, after the first intial start, (no problem there), no matter how long I ride for, (half hour or 2 hours), after shutting down the bike, when I go to start again, the battery might give me enough for 1 or 2 feeble tries and thats it! After that I'm back to the kick start. What a pain in the a--! Thats why I purchased the bike. E-start!! Anybody else with the same problem or any ideas? I have checked the rectifier output and that seems to be about 14 V. Thanks.
