I think People has same carb, runs better because has less restrictions early years. My 2005 People 50 2T runs great with stock exhaust, carb. I recently installed Tecnigas Next-R and runs even better. Read post by Art in People 50 forum for lots of good info, he's the People 50 expert IMO. Installing larger carb is similar to expansion chamber, will make more HP at higher revs, but loose torque at lower revs. For stop and go with 30mph top speed, you don't want larger carb IMO. Cheers
