ok, so I replaced the carb, sparkplug (was dirty), air vac tube, connected bike to my car, started, set idle correctly and everything looked good.
Put the bike back together, started it up again using car, great, everything seems good! Reinserted battery hooked up... ran and died... it would sputter... puff puff and die... I couldnt add throttle otherwise it would stall/sputter and die... didn't seem like petrol was getting to the carb at all (but it was)
looked at oil (Per skip) and it was too high, drained it a little and same problem... few more tries on start and it would start and die... which led to the battery dying... so what I'll do tomorrow is try the battery again (it's charging overnight) replace the petrol (drain old, pour new) not sure what else there is tbh...
On a good note, the owner of the place where the girl is staying has a Yamaha 750cc bike in his garage with 2300miles, wondering what it is and if its worth taking (buying) from him... I dont know what it is, all I know it's missing a throttle cable, its a kick start, carb is hard inside (may need new carb or rebuilt) below are pics, maybe you guys can tell me what it is and if its worth an investment...
