mmm if it's already idling at a thou and cutting out then sumfink else is up and raising it any higher is masking the underlying problem

Mine idles at about 800 -900 without any problems (97 - micron race cans K&N filter - dyno'd + rejetted)

Do your carbs need balancing?

As Wicky says, worth checking to see if your carbs are out of balance as that can make it worse

Some people say they never have this problem while others do.

If the carbs are out of ballance, how would you go ahead and fix, is there a A-Z "how to". Love to strip mine apart and fully clean up.

There is one (which makes it easy) adjuster screw on the left-hand side of the bike, situated between the carbs up in behind the frame, accessible with a screwdriver. You obviously need a carb balancer whereby you attaches it's vacuum tubes, one to each carb. That is bascially how it's done

No need to strip them for balancing normally

Common fault raise the tickover to 1300rpm cures it.

I've got a 'morgan carbtune'. Brilliant bit of kit for synching up your carbs. I use it on all my bikes.

I use one of these. Simple in design but IMHO does the job very well:-

I use the same carb balancer as sirch345. Fantastically simple and accurate.

The blanking plug on the rear of the fwd cylinder is a bit of a pig to get in and out due to access. Once i balanced the carbs, i left the adaptor supplied with the balancer in place. I fitted a short section of tube and blanked off the end. Made future balancing much easier. Have a very short handled screwdiver to hand to adjust the carb adjustment screw. Balancing now just a 5 min job

If you want to remove the carbs, its quite a simple job. Just remember you need to drain the coolant first. Be carefull when removing the carb tops as the slider spring is ridiculously long.
