trying to get my zuma running at altitude. after tweaking the air adjustment knob i got it to run, but it goes about 5mph slower now and if i'm going downhill it will throttle back even though i have the throttle cranked (at about 35mph). i'ld like it to run like it did in texas, but i can't find even an after-market jet for the carb anywhere. anyone know A) where i can find a size 89 main jet for the stock 90 zuma carb, or B) how i can tweak the carb i have to make it run leaner?
