What size snorkel did you run? If you ran 1.5" change it to 2" or install a smaller main jet.
ya wat marcust. said or in other words your runnin way to rich..
I ran 2 inch fles x hose from air box into 1 1/2 inch at the rack
Get rid of the 1 1/2" at the rack and use 2" should get rid of your problem.
Yup, you're choking your engine
thanks guys. gonna change that tomorrow. Would a k & n help?
Well guys, I changed the 1 1/2 at the rack to a 2 inch and not any better, maybe worse. With the 1 1/2 it would sputter and try to go dead in fourth and fifth gear and now with the 2 it does it in second and third. Whats he deal.
then that means your are running to lean so you will have to go to a larger main jet
