Thanks philward, yes, standard (original) intake, the gaiters and clips are in good condition, and the exhaust is standard HM340 except one replacement pipe to pattern. I'll adjust the needle to get the mix a little leaner.In the meantime I will take the medicine offered by Nurse Julie and confirmed by spitfire - I'll replace the plugs!
"WoooooHoooo!!!" Just tried the bike after installing the (non-resistor) Nippon Denso plugs recommended by Nurse Julie and....- the bike started first time AND on all 4-cylinders (that's a first!) - I tried it a few times just in case it was a fluke - and- it rides with the free flowing urgency I was hoping for.So far I have only taken it on a 20 mile test ride, but all is well. The spark plugs are showing a tiny bit of soot but I'll give the bike a much longer run before making any fine tweaks to the carburation.Looks like 7 years of miserable performance has been cured by 4 spark plugs. Thanks each!
