2 rides today to finalize carb jetting.
First a shorter of 70km. Back to garage, tank off and raised the needles 1 notch.
Back on the road and enjoyed a 200km ride, mostly in legal speeds except when testing how much better it pulls with higher needles when twisting from 4000rpm on 5:th gear. Same power up to almost 8000 rpm!
When back home changed main jets, 1 step smaller from 147.5 to 145.
Look forward to next ride cruising around in legal speeds, low fuel consumption, 53mpg.
Probably less if not twisting to check main jets!

55mpg is possible if riding 70-90kmh (43-56mph)

Those 147.5 Mikuni jets were earlier mounted in my stock K6 Keihin carbs with pods, 836cc, ported head and cam. Ran fine in the 80's. Not too rich! 3 long tourings in Europe.
Same jets too rich on my TMR32 carbs , same engine, now 1000cc

Strange.... Different fuel 30-35 years ago.
