Mods, which have been in place for years, are just wire splice (m-max) and Tyga pipes (stock airbox).
Jetting was done years ago on a dyno, worked fine for years, and hasn't been changed, which is the reason I am thinking it is not jetting settings. I guess I will try cleaning the carbs, though I've personally never done it and don't really know what I am looking for....never a good combination in my limited mechanical experience. Probably a lame question, but is there any way the carb gaskets or float settings could cause this or would I basically be looking only for residue or blockages of some kind....don't have access to compressed air. Thanks.
