I've made a few checks, the downpipes are all hot when bike is running, regulator charging at approx 14volts as rpm is increased. I've put on an alternative set of coils and the problem is still there. It runs terribly at anything over about 30mph shuddering and possibly spitting slightly, but well under no load. Considering my increased fuel consumption I was thinking that fuel wasn't the problem but now I'm thinking it might well be. Also because it's running so badly, impossible to get over 40mph I was thinking that it it's likely to be more than a spent air filter. Any input greatly appreciated and also how to check fuelling, pump etc. I had the tank off and fuel tap seems to be ok.
First things first - check your air filter. If it's really crapped up then you might well have these issues.
