Had recent trouble starting my Fe400e,adjusted tappets (closed) all good.One ride (4 hours later) bike did not want to start again.Checked tappets and lo and behold the gap has closed.I'm not a mechanic but does this mean worn valves ?
not necessarily. without knowing anything about where you are or the year of the bike (because you didn't put it in yer signature :wink: ) most likely it could be cam follower bearings or cam bearings. how long since they've been checked?
