if it conks out when you close the choke then your engine is probibly a bit bunged up - especialy if its a 2 - stroke because of the oil . if bike has been stood for a bit petrol evaperates leaving oil in engine. clean the engine just try with a small brush with petrol on if not strip it and clean it.

Wardy, his bike goes FINE when he puts the choke on ,that indicates an air leak as it then overcomes the excess air,look for split carb boot ,no air filter loose clips etc,etc,before having to strip the carb for a blocked jet Thumbs Up

I have the same bike as you.

Between the carb and air box there is a rubber ring which connects the two. On side is secured by a jubilee clip and the other side has nothing to stop its from slipping out. This is probably your problem its may have come out slighty. Take off your fuel tank and then push it back into place if it is out.

Hope that helps
