Yes. All Classics from MY93-00 can have their ECUs reset by this procedure.

Disconnect for at least 1/2hr for the capacitors to drain down.

Or alternatively, simply do it before you go to bed... then reconnect in the morning...

couple of mins to find its bearings should be more than enough and away you go but dont mummy cuddle it drive as you normally would so the ecu learns the way you drive mate
