Recently bought a used 66cc bike online. Gave it a tune up and fixed the chain brakes and new carb. I took it for a ride and the muffler fell off. Prior to that i could max out around 32mph. Ordered a new muffler and it now goes 18mph and bogs down. I took the muffler off and rode it around the block and it ran great. It topped out at 28mph but the idle was crazy high when the clutch was engaged. There are no vacume leaks and it does not appear to be running lean. Any help would be great.
