as far as for the info i got none but theres a fat psot where u can figure it out :D its on the 400ex info..

I have a 50 pilot in it, A/F screw is out 3 1/2 turns. I have a keihin 190 main in it. It was ideling smoothly, and was running good through the middle and upper rpm range until I bumped the chip. I'm may go back in and put a 52 pilot in there so I can bring my A/F screw in more, but all in all she running good. Now yesterday in Michigan it was rainy and cool. The temp was around 50 degrees, so I'm sure I have enough main jet. As it gets warmer I may have to bump it down a bit. There is a slight hesitation when you mash the throttle from idle, but it's not to bad.
