This is for a friend's bike that he got with 140 mains, a pipe, K&N,
and needles from factory. The midrange at Reno Fernley sucks. I
think the needles are too high, the mains too small and I am going with
either a stock filter for the 140 mains, or 150s with the K&N and
pipe. Also shim stock needles 40 thou and change pilot jets.
