Eyeglass blade screwdriver used to adjust the pilot air screws symmetrically prior to the throttle body synchronization.
Tip #1: For the E* & F (2000 - 2003) models, Kawi recommends 1 5/8 turns on the pilot air screws, although 1 1/2 resulted in an increase in MPG, as well as, better hot starting. At 2.0 turns fuel consumption increased about 20% and mid-range throttle response turned lumpy. Both my 9Rs prefer 1 1/2 turns and easily eclipse 50 MPG except under the most extreme riding. (see Fuelly.com)
On the E1/E2 models the airbox can remain on, since the three synchronization screws face towards the back. Noted in the picture are the clear restrictor tubes, whose job it is to even out vacuum pulses.
A closer look at both the restrictor tube inserts (note #4) and the vacuum nipple locations under the intake boots (1998 - 2003, perhaps other models too).
This last photograph is not necessarily relevant to performing a carb sync, but I wanted to point out various items that some of your 9Rs may or may not have.
1) Leftmost: see the electronic connectors for the float bowl fuel cut-off solenoids.
2) Bottom center: original fuel filter, at that time with 54,000 miles on it.
3) Top Center: fuel pump
4) Right of top center: California emissions plumbing (blue/blk tubing).
5) Bottom right: California emissions charcoal canister (black rectangle).

Alright! Trading bikes for a while was fun.I'm ready for mine back. No, seriously, get off my bike. Ahh, what a privilege it is to have such a sweet ride.
At the track she's said to be outclassed, but on the street, she reigns unmatched. She's the only big-bore canyon carving hypermiler I know of. -- Picture gallery
