Having a problem with, I believe gas flow. Bike idles nicely and accelerates nicely to about 3500 rpm in all gears and then begins to balk. Every once in a while it will get just past 4000 but then it seems to be gas starved. I've never done jetting but is this a jetting problem? If it needs more gas, do you go to a higher number on the main jet? the bike is supposed to have 130's but I have not yet checked the size. Had the carbs off and cleaned but forget the jet size. Hoping to look into it this weekend. Petcocks have also been apart and a couple of parts replaced so I don't believe it is the petcocks.
