Its not terribly hard to do a TBS once the tank is up.
Buying your own tool, (I have a Morgan Carbtune) https://www.carbtune.com/ paid for itself after its first use. (extremly well designed/built, IMO)
Just checking the TBS (no adjustment) is a bit faster than an adjustment. Yamaha gives you 10mm's of variance between the cylinders. Checking valves, NO adjustment(no cam removal/re-timing, etc) is much faster than changing a shim..
*Please take note that after paying approx $125.00 for them (a Yamaha Dealership) to do a sync, I later found they DID Not adjust the air screw (as should have been), BUT the butterfly SHAFT sync screw (specifically noted in the FSM NOT to touch). I found this as the screw / spring has white paint on it from Yamaha which was broken and obviously moved 1/4 turn.
The problem (under warranty) could not be found at the dealership and I later found it(with the help of this forum) on my 2004 as it was an electrical connector under the fuel tank turned green..
My current FZ6(4 banger), I have them within 3 mm's (some very fine, and time consuming tuning) but runs super smooth and got rid of all the low speed ( up to 4K RPMS), very annoying, seat vibs.
