two pot jota

Hope someone can help with this. Recently acquired. Nice 77 Jota and had witt fitted by stevio at calere. Bike was running fine till saturday when I fired it up and rode away. Above about 2000 revs it went onto 2 cylinders, the righthand pot going awol. I have changed the plugs and dropped the righthand carb floatbowl and all looks ok. I have swapped the right and left plug leads and the fault is still on the right so it must be carb related. Any ideas gratefully received. Thanks steve
 
Does it still run on 3 below 2000 revs?
If so sounds like a float needle issue, like it's not filling the float bowl fast enough for the demand.
 
...or simply water locking the right hand carb mainjet. had that on mine, too, years ago.

or a flake of rust is blocking the little mash that sits under the little cover on the carb where the fuel line goes on.

or an air-leak?

Also check the sliders are moving equally. sometimes the little hex-screw under the top cover that holds the lever on the actuation rod has unfastened itself and the lever does not really move, hence the slider does not or to late...

good luck!
 
Or the small cable from arm to slide.
