Hi all Need help. I have resurrected an old gsx 750 es 1984 model. I have replaced the cdi,coils,leads and plugs, changed the oil and air filter(stock item). She starts 1st time with a little bit of choke and runs fine through the gears. Red lines all the way but if I cane her for more than a few miles she starts to miss and just stops. I have to wait a few mins, she starts but on 2 cylinders and then starts to go ok after a few miles. Had a run out tonight and scratching around was ok but it happened again. On the motorway was running fine but the just conked out. Had to wait 10 mins and then it fired up on 2 cylinders, couple miles later was running fine. Seems strange that normal running and trip out to loonmies cafe she goes well but anything over the limit for just a short time and she lets me down.
