So today i fired up the old Puch Dakota because i have no tires left on my car. Had to get to a mates house, too lazy to take the bicycle. It started up pretty easy after a couple years of no use.
So heres the thing. It's got some goodies on there, bigger cylinder, high compression piston and some mods to the carb. But i thought id make an expansion chamber for it. But what thicknes should the metal be? Can it be "too" thick or thin?
