So after doing some research I can't find much info on any mods for a my moby 50v. As of right now that fastest it's gone is 42mph down a hill and 37mph on flat. I have a Dellorto sha 15.15 on it not exactly sure of the jet size. I know its in the higher 60's. I also have a chopped up baffle. Instead of the long pipe it just a nub at the end. Well anyway. I've looked at the gas spring mod and a few other things. What mods are out there and how effective are they? I'm trying to break 45mph on flat ground. pic of my moby Thanks!
