After going round Jambos last night and him giving me some of his time, illumination, tools and tea I have sorted a number of things. The throttle is like a greased ferret when I turn it now, so much so that I forgot how it was meant to be. So thanks to the pressure cable oiler for that. We have gone round the bike and checked all the earth and positive cabling on the bike to the battery, frame earth and coils, all seem good. Spark plugs where cleaned and gapped by Jambo but they where in a reasonable condition to start with. Then the carbs where inspected... which is where the problem lies, now the balance seems fine with only a small difference.

The main problem seems to be the jets, namely that on the front jet on the slider at idle you can clearly see fuel being 'jetted' out. Where as on the rear it is only viewable when the throttle is open, both increase with throttle though. I will post a pic of the jet in question if people are not sure but we suspected it as the source of my bad running problem, namely low revs at startup even with the choke on till it gets warm. High speed power lose when throttle is opened fully above 6k, plus 'some' problem with the engine almost choking off if I open the throttle to quick from a start with out reving first.

Oh and thanks again Jambo...
