Well I've been running tech on cleanrer through the system, slight improvement in idle quality but still makes the same noise. I added a bottle of octane booster to see what would happen, still doing it. I think now I've been carefully listening that it also did it when I released the throttle from mid to high revs. Next step - O2 sensor (seeing carbon on the exhaust), timing and valve clearance check.... Thanks for the suggestions so far - getting through the process of elimination.
Oh - and I may have been lugging it - I've come from a Honda VTX1800 V-twin which has huge torque from almost any revs, so now I've been paying attention to keep it above 3500rpm always, and gave it a complete rev in 1st and 2nd (this this is quite quick....!!).
