Evening all, when out in the S2 today ive noticed that when going along at a steady speed (say 60) the rev counter seems to be fluctuating a little bit? not bouncing all over the place but just going up and down between a couple hundred revs? also have recently had the old back lights flickering issue which a mate noticed when following me down to Central day but ive cleaned all connectors etc and they are working fine again now

could my rev counter issue also be down to dodgy connector/earth etc
Matt
