400 EX starting problems
Can anyone give me some advice, my 400 EX dosen't want to start since I put on my new pipe, I have a KN, 152 main jet, Procircuit T4, Alba rev box. When you crank it over it fires but won't stay running even at full choke. If you rev the crap out of it till it gets totally warmed up it will idle fine. Today I got it started was revving it up for about a minute with a little back fire or sputter then it died. Then it would not fire at all. I took the plug out it was pretty black, I cleaned it up, put the plug back in and it fired right up as long as I kept on the throttle. Then it died again and it won't fire again. I just left it at that and here we are. Oh yah my header gets cherry red too until you can get the B*tch to idle. Please help!!!
