I bought my first bike, a 80 CB750K. I have not been able to ride it all summer due to charging problems which I have narrowed down to a shorted out rotor... Hopefully. Thing is electrosport wont have my part for more than 10 weeks from the date I ordered it. Also the bike has very little power. I rode it home 90 miles barely able to reach 60 MPH. It will only Tach up to 6000 RPM with no load. If I pull the plugs while running .. one at a time each one will kill the engine leading me to believe they are getting spark. The #1 and #2 cylinder on the header never get hot though. Why would both of these cylinder not be firing. Is my charging issue and spark issue related? Any help would be appreciated.
Thanks
