The problem is this: The engine works perfectly for 20 minutes rideing.I take my hand off the gas then and is banging and when I pull the gas then is gasping for breath.Like that as if a lot would get petrol but no.the carburettor and the ignition perfect.
I exchanged the spark plug erröl: NGK C8E this way:CR7E
Thanks for help!
