I have a 01 XRL and find that it may be lean, what are the factory jet sizes 49 state model? I have added a Uni air filter to the bike and the rest is stock, haven't uncorked it, plenty enought for me as it is. Juut want to make sure its right, do I need to change jets or just adjust the air screw? Elevation is 1000 feet abpove sea level. I can't really find anything in the search files that will really answer this for me. Thanks for any responses, Porkchop.
