Honda Spree and Elite 50 Forums

I changed the carb and the bystarter also the exhaust but the engine boggs at higher speed, Runs fine a the low end but when i rev it up it run s well for a few seconds and just boggs down while the thottle is wide open.Anyone have a clue?

mine was doing the same. i took of the exaust and cleaned it out the best i could and now it seems to work fine. also just try running it wide open for a few minutes to help burn the exuast and clean the insides. also can u see somke when u rev it up.
