Does anyone know of an illustrated guide to which screws should and should not be adjusted when doing the throttle body balance / syncing? And does the tank need to come off / be lifted up to do it?

It's fairly well documented in the workshop manual for the 2 valve
They are M6, most balancing devices come with connectors. But I made my own by drilling an M^ stud down the centre, then fitting a nut halfway.
To balance at 3 or 4k rpm you adjust the linkage screw. You shouldn't touch the individualair bleed screws at anything other than tickover.
There has been lots of discussion on the high tickover when warm. Most common answer is to put a tap in the air bleed supply from the air box to the stepper motor and turn off when warm. Needs to be open for cold starting.
Ah right, there’s the error then. I’ll rinse and repeat tomorrow.To balance at 3 or 4k rpm you adjust the linkage screw. You shouldn't touch the individualair bleed screws at anything other than tickover.

Well, condolences on this frustrating struggle.
