The procedure is not easily described. You can do some searching on the net for setting the "balance" or "sync" on Keihin FCR Flatslides to see if there are any pics.

Something I would do which is a good starting point and is very simple, would be to use a "feeler gauge" to adjust all the slides to the same opening with the throttle closed. If that has never been done correctly it alone can make a discernible difference in the idle and off/idle response.

Also, of course make sure that at full throttle all of the slides are open fully.

Yes, mechanical synch and then start it and fine tune it while its running and get them all clattering together.

I need to sync my VGAS carbs, and I got admit, that link above is alot of information to try and comprehend. Maybe somebody could dumb it down for me? I've sync'd stock VMAX carbs, surely it can't be THAT much more complicated? :ummm:

Thanks Weasel, this looks good! unk:

Then I got to the troubleshooting guide:

Problem: Incorrect synchronized throttle valves

Solution: Synchronize throttle valves

OK........
