quick tip to try in seconds, take the hte leads of each plug and spray wd40 in each end. let them soak for a couple of minutes then put them back on the plugs. Could be simply corrosion or dirt built up in the plug caps.
Sorry, my readings were crap. I took another reading today. 1250 and 1300 rpm is the margin of fluctuation.
When I bought the bike I replaced: Fuel filter, Air filter, all plugs and balanced carbs. carbs we thought were ok, difference of no more than +/- 10 across all 4, as per shop manual. I sprayed caps and all accessible (seat, side covers, signals, tank etc.) loom connectors - with Holts Contact Cleaner, let drip n dry, and all was well.
A guy at work has just suggested its my style or roads (I use 'B' roads with scrappy tarmac) or thin fingers and poor gloves perhaps because he remembers me complaining about numb fingers on my previous bike.
