I was just wondering what is the best place to buy jets? I couldnt find them at the tt store and my dealer says he can only get stock. Also, with humidity, do the bikes need to go leaner or richer? One more thing, can anyone explain the purpose of the differant types of jets? pilot,main air, main, leak, starter etc.. Thanks alot, D :)

I called sudco and they asked me the dimensions of the carb. I tried to find out at yamahas web site but they only showed specs for the'05 and'06. Does anyone know the dimensions for an 03 wr450?
