Did you rejet the bike when youchanged the pipes? What pipes were you running before you but the new ones on?

[4milstrkr]

stock pipes and yes i did rejet but i put the stock pilots back in because it would run even worse but carbs are syncronized and the reeds looked fine when i rebuilt the motor this summer and it doesnt have an air leak anywhere ive already sprayed it down

What are using for fuel? What is your static PSI?

Well if it is hard to start cold then it sounds like you have a lean condition. If you are running stock pipes with a 4 mill you are costing yourself a ton of power. What carbs do you have and what jets are you running in them? Also what elivation are you riding at?

i have pro circuit pipes now im runing 93 octane and psi is 135 both cylinders

What carbs and jets?

310 mains stock needles and pilots took stock pilots and needles out to see if would make it run better and it didnt i just rode it lastnight and the left side pipe only fires every now and then until u go above 1/4 throttle and my elevation is 600ft stock carbs
