yes you need to rejet, your bike is running lean. did the pipe come with any jets? if not you need pick up a couple differet sizes. Without a snorkel I would try using a oem 132.5 jet. You should be able to pick up at any atv shop for around $5 or so. Most dealers dont carry them.

thanks im goin to try a 132 cuz i cant find a 132.5 and a 50 pilot jet in it and hope it works better!
