Can anyone help ?To pass the sva emissions test i had to wind the mixture screws right in to get it to pass.I have now reset them roughly 2 full turns out on each carb,but would feel happier having it tuned to make sure the mixture is right,was going to use holseshot racing but £200 sounds a bit dear to me for a couple of hours work.The engine is a standard Yamaha thunderace engine 1000cc.Does anyone now anywhere in the northwest area who can do a rolling road tune and possible rejet if needed but i must admit it dosnt seem to be lacking in performance so may not need the re-jet. I live in the Rochdale greater Manchester area.

Automech at Irlam near Manchester have a rolling road, I've not used them yet but they may be worth a ring if there's nowhere closer. Tel (0161 775 1851).

No connection.

Cheers,

Colin
