Hey Dennis, thanks for all that sweet sweet info, I think I will do the vacuum gauge sync next time working on the bike. Seems like it will clear up more questions and hopefully solve my issues.I was actually wondering if there is a proper methodology for the mixture screw settings. I know that the look of the plugs is a telltale sign but I was wondering how precise it gets without requiring an IR exhaust gas probe.Cheers!
On my 400F the air filters and exhaust are non standard and I have an Innovate Air / Fuel Ratio guage already fitted which was very useful during re-jetting and setting up under actual running conditions on the road. The settings I have used are to deliver best power, torque and engine temperature, with no specific regard to economy or plug colour.

Just to report back I seem to have cured the problem - I took the carb bodies to work and gave them a good blast with compressed air, fitted the new seals, and reset the float heights. So one (or a combination?) of these made the difference - my gut feeling is the float heights were the culprit. Thanks Alex and everyone, hopefully I won't need to take those carbs off again anytime soon!
1/8 inch is 3mm not 0.15mm
I did indeed! Even found an actuall drill bit that is 0.15mm (1/8")
