So I picked up this 89 and I'm having a little bit of issues I want to clear up So it has a keihin 35mm single carb with no airbox with a k&n podfilter it also has cpi in frames on a stock motor currently elevation is 1700. Just seems like it lags a bit on throttle but gets going after I run it up the road any idea on where my jets and all that should be?
