Time for my 1st valve adjustment and while the mechs are in there, thought about putting in a set of cams. I need a recomendation on how much "cam". I need the bike to be reliable and idle. I don't want mileage to be hurt too terribly bad, as I sport tour this bike as well as run it at the strip. Is there a good cam out there where I can feel the performance gain and still keep reliablitly??
