Ok everyone my bike has officially driven me crazy. I knew better then to mess with the carb on my 03 yz450f. So anyway, here it is, any help would be greatly appreciated. So I put a boysens quick start on my bike and an air adjust screw and a new cap for the hot start cable to enter the carb onto my bike. Now that I have done this, I simply cant get it to run right, I mean it barley runs at all. I don’t know if I stretched a cable or messed the hot start up or simply cant get it adjusted right, but after some adjusting, I can get it started, but it gets super hot I mean my pipe starts to glow bright red, so I turn it off. While it may run if you hit the gas it will stall or snap and sputter. Please help someone, as I don’t want to have to pay the shop. Thanks all.
