SOURCE: Carb Sync on an 01 YZF 600R
Here is a diagram showing the tubes you connect your vacuum gauges to.

The YZF600R is carbureted, so I do not know what you mean by throttle body adjustments.
Synchronizing carburetors means adjusting the throttle plates (butterflies) so that all cylinders are drawing the same amount of vacuum.
Here is a diagram of the carbs. Screw #31 is the screw used to change the sync.

Remember one other key point, all carbs are sync'ed to the #3 carb. You cannot change the vacuum (directly) on #3. It is usually best to start by syncing #2 to #3, then #4, then #1. Changing #2 can affect the sync on #1 so you definitely want to do 1 after 2 no matter what. If you have one cylinder WAY out of sync, that would be an exception to the previous rule where you would want to attempt to get that cylinder in the ball park of the others before fine tuning each cylinder.
Syncing the carbs is an alternating process between adjusting the vacuum then adjusting the idle. If they were out of sync, bringing them back in, or even getting close, can cause the idle to raise because the engine isn't fighting itself anymore. Always keep the engine idling @ 1100 rpm's while syncing.

Try phpBB FZR250.com. Each section of the manual is listed but its in Japanese, aparently an English version was not produced. It is detailed and has torque settings. Hope this id helpful.

Sounds like the bike has been doing wheeles and burnouts. As the clutch plates wear the cable needs adjusting. You have reached the end of the actuating cam. New plates are your best bet.
