when refitting the needle jet yesterday it appeared to seat further in than I remember the last time, I think this could be the bulk of the problem
the bike is running cooler, not a plug chop but plug condition is a very clean light tan, I just used 1.5 turns out on the pilot so need I'll get the colourtune on it, rolling off the throttle I get a small 'skip' so the pilot may need the adjustment
top speed is still poor, sits at 55 ok but not much more, I was hoping for 55 as a solid cruise speed for the motorway
I've noticed a light ticking from I think the right side of the engine, will double check the valve clearances in case I buggered that up, I may have the exhaust off and replace the manifold seal just by way of precaution
thanks for the offer of a carb, I may take you up on that
the bike is very much better than it was, I suspected old fuel originally hence the ultrasonic but it's very very clean now!
does anybody have experience with the 'air suction valve', I understand it's used to 'afterburn' the exhaust gases, I'm not up to speed on theory of operation but could this cause running issues
appreciate the help
