I have tried searching various posts, but have not found the answer to my specific question - so any help would be appreciated. Just installed YZ450 Cam in my 04 WR450. The bike runs fantastic (and I recommend the mod.), but it will not start when using the electric start - why? It seems to be cranking just fine, but it will not fire-up. - Battery Checks out good and has full charge - Starter cranks and engages (sounds strong) - Grey Wire pulled - I have tried when bike is hot/cold and anywhere in between - It will kick over in 1-2 kicks - I have owned the bike since it was new and e-start work perfectly just before the modification It really is no big deal to kick the bike over, but nice to have the e-start - it does come in handy at times. Thanks!
