Thanks for all the replies, have not touched the jets as yet a I was advised leaning the idle/pilot airscrew on each carb would do the trick by a well know Triumph expert/part company.
Only problem was looking up at the jet I could't see the slot for a screw driver. I assume I have to "obtain" the D-tool mentioned by NIbiker. Is it a service tool from Triumph??
Cheers
Kenny
