Yamaha DT 50 MX 86' Stupidly I let my bike run out of 2 stroke oil, We then replaced the barrel + piston and since then it has worked but never properly, Ive checked the carb, points, fuel, spark plug, spark literally everything even brought new coils for it. When riding it seems like its running out of petrol but I know for sure that petrol is getting intro the carb, I cant describe how it runs the wod that comes to mind is inconsistant. Another problem is when it is finally working (rarely and only for 5 mins) I would be going along then it would sudenly just cut out almost as if somone had hit the emergency stop?!

Advice and info would be much appreciated...

regards

have you checked the condensor, the heat may have damaged it. also chech the allignment of the flywheel to the stator. inrotating the flywheel there should be a clearance of a sheet of paper. check for a clearance increase or decrease when rotating. you may have bent the crankshft.
