I just received my Yoshimura TRS street slip on, and I check the Yoshimura website if the bike needs any adjustment or tune up, since it'll be exhaling differently now. They suggested, "it is important to at least adjust the pilot mixture screws and shim the needles 0.5-1.0mm..." for slip-ons. Now how exactly would I know it's tuned to meet the requirements of the exhaust, how would I measure the calibration ? I am trying not to get the bike to run too rich or too lean, in fact, I like the current state of lean flow. Thanks.
