Ok I just bought A KN airfilter for my v-force and I am going to do the napa hose mod to it. Now I have one of those hmf slip on pipes I rejeted it for pipes and I guess I will have to rejet it agin with the new parts coming in. Now my question is what jets would I have to put I now ? I live at sea level also. THanks

 

Depending on your jetting now, you may want to shim washer the stock needles with .020- shims. Are you running 142-145 ? Read your plugs. Where are your pilot settings at? Does it pop, burble, stall, flat spots?
