Carb syncing

Hey all

Just wondered what rpm range you guys sync your carbs at. Idling at tick over or at a specified revs?

I synced mine from idle the other day and I'm not sure if it feels better (smoother) or not. They was out by one increment on my cheapo (round dial type) type gauges. They tended to drift out of sync slightly as I blip the throttle then setlle at idle in sync again. If I hold 3-4k rpm they go out of sync.

I'm going to have another look tomorrow, got a mate popping round to take a look too.

Should I sync at idle speed or sync from 4k rpm?

The Haynes manual says tick over but they could be wrong. They also mention that valve clearances should be checked. Could my symptoms mentioned above be caused by worn clearances on the inlet valves?

Thanks

i did mine last week at around 2000 or 2500rpm i think. I was also out by approx >2 cmHg measured with the morgan carbtune. I got it leveled out exactly and for the next few days of riding i was convinced the engine ran a lot smoother with a lot less vibration in the mid range. The engine also seemed happy idling down below 1000rpm.

My next mission is valve clearances...
