pulling away issue on mk1 fazer

[ghostbiker]

Power is good. If I slow to almost tick over and pull away again it's the same issue as pulling away from standing start. Less noticable as the bike Has momentum.
Not a clutch issue I'm sure.
Everything's operating smooth and clean other than that specific rev range.
You only really notice it in first as there is no momentum to the bike so a drop in revs almost stalls the bike. Once moving it is still there but only just noticeable if your looking for it and that low in the revs.
Plug caps are OE as far as I know
