these are interesting posts.
i learn something every day!. Now I know each moped is different, but here we are talking about hobbits. Im really glad for the guys and gals that are modding their peds up to get 37mph on the flat using proma pipes and doing jet mods, but its seems like minimal gains to me :(
additionally, the 70cc kits and bigger pipes tend to reduce gas mileage. Currently, I have a stock honda pa 50II and reach speeds of 37mph easily on the flats. With a long enough flat, it will go to 39. No jetting, no performance pipe, the only mod was to notch the variator as recommended by justin C. on this forum
I weigh 190 lbs, and I dont know why other hobbits (pa50II) are going so sluggishly?
