New 08 WR450. I've had the battery replaced already - wouldn't hold a charge. I put the bike on a battery tender nightly. This Sat. the e-start was good and strong at first but then after just a few starts (6-10) the battery petered out and I had to kick it. I'm new to trail riding so I dumped it a lot that day over logs, steep water crossings, stuck in off-trail junk trying to go around a fallen tree,.... Got more and more tired and after a while just kicking it was a chore!!!! I was beat man, just plain useless. Too weak to ride. My buddy picked my bike up for me after one particullarly good (but slow) tip. Embarassing that was, but much appreciated. Anyways, anyone with a similar issue?? I'm not sure it's normal. I think from now on I'll kick it early in the day and save that nice e-start for when I'm wiped out. Need to do some pushups. Darn!! 41 can feel old.
