Hi peeps, over the last year I've noticed my idle revs have dropped to just over 1000 revs, bikes done 17k miles. I didn't adjust the valve clearances at 12k service, but am planning on doing them at 18k, would valve clearance have any effect on idle revs? And how the hell do you get something on the idle adjust screw??? Any thoughts/advice greatly appreciated.
