Cheers Chalk..I have been out and about Derbyshire today and noticed two things,apart from the beautifull scenary and cold that is.

After adjusting the Kev fuel mod back from 6 to 5 the bikes pulling smooth and crisp. Very happy.

Idle has dropped and that combined with the clutch query too much slack I stalled the bike at slow speed manoeuvers in traffic four of five times..sphincter clenching moments to say the least.
