Gen 1 Fazer cutting out / dying

[ghostbiker]

Check air intake and filter, start with the basics and cheap stuff. Check everything is working as it should be. Are plug caps tight, lose plug?  Mine started to stutter at high revs last week Nd at tick over I could hear a slight puff of air as it ticked over. Turned out number 1 plug had worked lose and was only in by a few turns.
