Sounds like the twistgrip cables hanging up or the twistgrip itself needs grease?

Or the grip itself is spinning on the handlebar?

Had a 'lurch' and it was into traffic- pretty un nerving.

Looking at the plugs the colour seems to be spot on, both plugs are identical.Also i have turned both richness screws out the same number of turns which match the manuals advice.

Hello,i will let you know about the mixture setting soon,i have just fitted a pair of 'peashooters' and a set of unbalanced headers and i can tell you that it's released more low to mid power than the standard cigar pipes did,and the sound is pure British now,wow!
