Hi guys. I need some help with my bike, can't figure out the problem. WR450f 2005My bike starts up fine, also the idling is right. But when i go on a straight (300m or so) and when i give it gas and go really fast (3rd or 4th gear) the bike just starts to die, or stall. Almost like it's running out of petrol.And this only happens when i really give it alot of gas. It also happens when i ride slow (2nd gear) and keep on going for like 3miles or so. Then it does the same.And then the bike would not start. I have to wait like 5-6 minutes.Help will much appreciated!Thanks! i also posted this at the "general descussion page"
