Underneath throttle body there are 3 screws. The one between 1. and 2. throttle body is for sync that pair. The one between 3. and 4. is for that pair. The one in the middle syncs left and right side of throttle bodies. :cheers:

Just to add to that, I'm pretty sure the middle one is accessed from above.

I checked the 2 outer adjusting screws are underneath and the Center one is accessed from above.
@Hooli your correct.

It'll run smoother at low revs & have less clutch rattle if you did it, unless you're amazingly lucky & it's stayed in tune.

Just reading this thread & saw your comment Hooli.  I just did mine a couple of weeks ago, only took it out for a reasonable run the other day & ya know what? I thought to myself, that's gone into first without such a heavy clunk & it definitely was smoother going slow round corners at low revs.   I wasn't sure why it was different, didn't think it was that far out of balance to make any difference, but it must have been. Even small differences between the cylinders would appear to make it 'less smooth', wouldn't go as far as to say rough, but noticeably smoother when all are reading the same.

I used a short stubby Philips head screw driver on the 2 under & because the PAIRS system is gone, it was easy as access to the top centre screw - longer Philips screwdriver for that one.  Pic below of the finished job
