Has anyone had any problems with taking out the choke on your EX carb gas fouling when it is idling? My brother drag raced Banshee's and I told him about it and he said at high RPM it is a good cheap cheap mod but idling or lower RPM's it will hurt. Is it true or not? Thanks

I would say not true, I have done it and have not fouled a single plug. If you have not done it yet, change out your pilot to a 42.

Ok thanks, I'm in the pI have to get to town so I can get a 42 pilot.

With the 42 pilot is that for a stock bike or all or what? I have a 416 10.5:1 JE Aftermarket header and muffler hot cam stage2 KN w/ no air box and big gun CDI.

I think that is pretty standard, if I remember correctly that is what Rico is running is his and he has a big bore.

I aint got nothin on mine but a pipe and thats cause I picked the POS up for $50. I have major plans for my ex so I am getting the little stuff done first. I am thinking about tearing it down tonight and repainting it cause the frame right now looks like crap cause it wasn't took care of. I'll post some pics of it.
