I took the pwk off.Im done with that carb untill i get my head mod done.Put the stocker back on.It ran so much better.Make the pipe super zippy in the low to mid randge.But the wierd thing is.I can go up to 240 main,it doesnt load up and choke its self out.But it is super lazy.To get it to pull hard i had to go down to a 200 main Almost the same as my Fmf! Im going to make a video in a little bit of some high speeds runs with it on!!
