Kinda O/T, but I thought I'd give it a try anyway. I've got a 1982 Honda Urban Exress moped(vintage by most moped standards ). 49cc, 2 cycle, miniture CV carb, centrafugal clutch, etc. Problem is it tops out at 23-24 MPH(30 downhill with a tailwind). Being that slow, I'm always in the way of other motorists(not good). Are there any cheap and easy things I can do to get more top speed out of it? I tried a velocity stack instead of a filter, that didnt help. I fiddled with the jetting a bit to no avail(went slower with both more jet and less jet). I turned the mixture screw 1/2 turn at a time, and it made almost no difference. Any tips would be appreciated. Thanks.

Right on target but all involve some more work than you may want to do. Pull a few teeth off and stretch the flex it will give you more on the top without killing the bottom

Thanks for the info. I'll keep you posted on my "Results."

What do you mean by "pull a few teeth off and stretch the flex"? Have anything to do with the clutch governer under the primary pully?
