Hmmmm all very strange, I hadn't actually removed the carbs but checked the cables and made sure they were closing properly. Dunno if upon looking I had done anything but it all seems well now, reving and ticking over, so a big thanx to all.!!

Mine is running, sounding really quite cool, big throaty growl, but the cylinders still seem to be in the huff with each other and "hunting" I think best describes the idle.

If the carbs wouldn't balance up you need to check the idle mixture screws and the valve clearances.

Idle mixture and valve clearances???? eeeee god the plot thickens, gonna try and get a working set of gauges and try again, hopefully that will be all that is needed.

There is also the possibility of knackered gauges!

Bear in mind the reading is pulsing naturally (4 stroke cycle, innit). Did you have the damper screw closed far enough?

Yeah I turned it as far as it would go one way and then tried it the other but they still fluttered or rather spun round this way and that. I think the gauges were err very cheap off flea bay so I'm happy enough to presume them duff.

I don't get this at all!
I've taken the air box off to get to the adjuster screw on the carb and now it won't tick over and if I rev too hard it just cuts out. I had another go with the gauges, as pointed out to me I hadn't set them up properly (tube into valve then into gauge ) but now it won't tick over at the appropriate speed for me to adjust.
Can I rev a little and adjust from there or does it have to be done with no revs at all?

Turn the idle adjuster up a bit, it makes it far easier to have a stable idle.

Just a quick update, apparently I'm a male sexual organ.
When adjusting the carbs, the tank is up and disconnected, so therefore after a wee while it runs out of petrol.
DOH!
Anyway all done now and running sweet.
Thanks for your time a patience.
I'm gonna hang my head in shame now. (scuttling away into a corner donning a dunce cap)
