Just a general observation for anybody chasing a misfire or stutter. During my investigation I cleaned my carbs, replaced my plugs, replaced fuel filter, cut back my ignition leads did a carb balance none of which did anything. My symptoms only came to light after riding the bike hard for a few miles and then she would misfire on hard throttle at low revs. I would recommend anybody who has a misfire symptom to replace the plug caps. You can get 4 NGK replacements for less than a tenner.
Another possible red herring symptom is a rough idle. I have a K+N filter and a Beowolf end can with baffle in. Even after doing all of the above my bike still doesn't idle smoothly but rides great so I'm not worrying about it.

How can you have "hard throttle at low revs"  :look

Maybe I didn't explain it right. After riding hard for a few miles, if I had to slow down then open up the throttle (low revs, high gear) at anything more than about 1/2 an inch then the bike would stutter/misfire. If I eased the throttle extremely gently then I could get the engine to pick normally. You can pull the throttle around hard at any revs. The gear your in will decide how fast the engine picks up.
