I recently bought one and the first thing i would like to do is well upgrade the carb I don't know jack about bikes so i figured getting this bike would be a good starting point. I cant find anything around google I see videos of people who bought the a new carb but they never link or make a follow up video to see if it fit/work. Could anyone help by suggesting what carb to buy that would fit or if so do I need to buy a manifold for it. Much appreciated.
