Ok I emailed jets r us and got no help.is it really this hard to get stupid damn jet needle?I've called four dealerships with no luck.can anyone tell me according to the part number "nr1173" on this broken needle what I exactly need?I've looked the engine over and everything was running good from the looks of the plug and the top of the piston so id like to just put the same thing back in it.please help I'm starting to think about scrapping this keihin in favor of a mikuni since parts are readily availible.that chart on jet r us has me stumped.
