I just completed my 1000 klm initial service on my 09 FZ6R and thought others might like the run down on sync'ing their throttle bodies. If you are handy with basic maintenance, you should not have problems performing this service yourself. First, you will need a sync gauge. There are many varieties of these gauges available so follow the instructions included with the gauge. I am using an older mercury gauge, but the basic principles are the same. If you have never performed this task before, it is good to have someone show you the ropes for the first time. If you already know the ropes this post will be a quick familiarization to the FZ6R's set up. Yamaha has made this much easier for us than in past models (Kudos to the engineers).
Tip: The instructions for sync'ing throttle bodies from the 07 FZ6 manual (available if you search this site) are very similar to our FZ6Rs. Note: I just finished changing the oil, so my pictures show the left side faring removed. You do not have to remove the left side faring to adjust the idle and sync the throttle bodies.
First, you need to remove the passenger seat, and then remove the driver's seat:
Next you have to remove the two panels on either side of the tank. The front of each panel has a quick disconnect fastener. You have to reach up under the faring and push the centre plunger up to release the fastener. The rear of each panel has a hex bolt. After you have the fasteners out, then carefully lift the back of the panel and pull back. The tongues at the front of each panel may require some careful angling to get them out without breaking.
Here is the quick release fastener with the centre plunger up so it can be released
Now that you have these panels off, remove the two hex bolts at the front of the gas tank
Once these bolts are removed the whole front of the tank can be lifted up. Now support the front of the tank securely with a piece of wood (aprox 16" long) or something similar that will not scratch your paint.
A good idea is to place a large fan that will blow air directly at the radiator to help cool your bike as we make adjustments. If the engine starts to overheat, you should shut the engine down to allow it to cool. Most of the adjustments are quick to do, so this really shouldn't happen.
Once you are sure your tank is secure, and your fan is on, you can now get at the idle adjustment on the left side of the bike just below the air box.
Start the bike and allow it to warm up (64 -74 degrees C should do it). You will hear the idle level off at its lowest point when it is warmed up. Now you can adjust the idle screw shown in the diagram above (Yamaha Service Manual, 2009) to adjust the idle between 1250 - 1350 rpms. -Updated July6/2010 to reflect idle adjustment correction. My thanks to Butcher Bird who caught this error
I have mine set so the tach needle is just below the first mark after 1000 rpm. Once you have the idle set then you need to hold the idle screw steady with the allen key while tightening the lock nut. Once you are satisfied then turn off the bike and you are ready to hook up your sync gauge.
