not enough play at the moving parts when hot.As a number of you will know recently I have been looking at and working on the Lucas ATD fitted as standard to our Vincent bikes.
After a full refurb of my ATD that included new and stronger springs I find that more often than not it performs perfectly for around the first 200 miles immediately after the refurb but after that, when the motor is cool it still works well but once the motor reaches operating temperature the motor is very reluctant to return to idle. With the bike in gear I can slip the clutch to get the motor to idle, but then it returns to much higher revs when the clutch is pulled in or the bike put into neutral.
I suspect that for whatever reason the ATD is not returning to its fully retarded position. I have rechecked the ATD springs and they are pre-loaded in the retarded position.
Anyone else had/having this issue? Any suggestions?
