Default Re: 5 bikes in 9 months

Allen... I had trouble tuning my CNS carb until I pulled off the vent tube on the back of the air cleaner. I think that tube is put on in such a way that it sucks gas out of the fuel bowl, and messes with the air/fuel ratio. I tried different needle settings and 8 different jet sizes, and nothing worked good until taking off that vent tube. Now I'm back to the factory carb jet, and running great. Check out the CNS carb tuning posts on this site.
