I have the same setup, trinity stage IV 2 to 1 in take and I run a 180 main jet and needle clip on top slot. and my bike runs perfect. I'm in florida were it is always hot, I don't know where you are at............ Quote
motavated Posted January 13, 2009 Author Report Posted January 13, 2009 im in ky stays fairly cold low 30s in the winter not sure what a plug chop is? it feels slugish on the big end like its starving for fuel Quote
fastbanshee8 Posted January 13, 2009 Report Posted January 13, 2009 Pull your plugs, and look at them, then let us know what color they are, so someone can help you out. Quote
motavated Posted January 13, 2009 Author Report Posted January 13, 2009 alright it looks to be a little purple and black Quote
fastbanshee8 Posted January 14, 2009 Report Posted January 14, 2009 If the plugs are black, you are too rich. This is probably why it's not running right up top. Go down 2 jet sizes, and run it, to see how it acts. If it was lean, the plugs would be white, or light gray. Before re-jetting, start it up, let it warm up, and then pull the choke out to see if it runs better, or worse. My guess is, it will run worse. If it runs better, you're too lean, but if it runs worse, it's too rich. Quote
