Did ye ever change the plugs out for new.....seem tae mind ye said didnae do the front one.
From an experience heres a possibilty?......ma youngsters SV650 ( wee V twin) started stutterin, wi the front cylinder droppin off and on but only very intermitently at first so just felt a bitty rough and seemed more certain revs ( yer flat spot?). As a result neat unburnt fuel was passin thru and actually igniting in the headers and exhaust and was a bit reeky and sootin up the can.
Turns oot it was the front plug failing (which finally gave up the ghost totally so it was running on the rear only,which wiz nae fine on a wet pissin doon night when yiv jist stepped aff the IOM ferry!)
On the SVs the front cylinder plug is wide open tae the wet and awe the road **** so was pretty corroded.
A brand new set o plugs sorted it and its ran fine ever since.
Jist a theory so dinnae shoot me.
