hi folks, just today i bought a 94 cb 750. it needed the pipes refitted and the battery is totally stuffed. but shes a good buy at $650... i refitted the pipes and took it for a ride...the fuels possibly 3-6 months old. the battery was totally dead and one pipe has a really bad dent in it. when i rode it she seemed to be bogging down real bad under acceleration... it seemed to idle fine and revved great on the spot but no good under load. could thid be the flat battery affecting it or the dent in the pipe? if not either of those how about the stale fuel or even blocked up carbs? any help greatly appreciated!
