Hi guys. I need some help with my bike, can't figure out the problem. WR450f 2005 My 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!
