I just switched my automatic clutch back to a manual clutch. When I ride it aroung flat areas the bike is fine, but when I go into the technical areas like hill climbs and bumby terrain the bike starts bogging. I checked the float bowl and it's in specs. Also when i press the electric start the bike sounds like the battery is dead so I bought a new battery and same thing. It will start the bike but it's cranking real slow. Any suggestions.
