Everytime I'm going down hill, slowing down or running on momentum and I'm not on the throttle, my bike is back firing like a large bore hunting rifle. Could it be because of fuel starvation or a lean air:petrol mixture.
There doesn't seem to be a problem when I give it a wrist full though. Maybe a bit boggy at low revs but thats about it.
I also seem to be getting some mega milage out of a tank of petrol.
Any suggestions please chaps on what may be the cause and how to fix it
