... the entire air filter assembly must be removed. Access to the front cylinder's spark plug is completely blocked by the air box.
I took mine apart yesterday for a throttle body synchronization and changed the plugs while I had it apart.
The air box TOP easily comes off by unsnapping a few latches and removing one hose. It slides off to the right (after a little finagling). Both right and left side pics are below with notes:
The LOWER part of the airbox is removed by (1) removing one hose connection, (2) cutting a few cable ties and (3) unscrewing six Torx-head bolts which connect to the throttle bodies through the bottom pan of the plastic airbox. Note that there is limited clearance on a couple of the Torx bolts.
After the removal of the air box (both top and bottom), the throttle bodies are revealed in all of their glory
:
There's nothing to adjust on the throttle body sync other than evening out the vacuum between the two bodies. The butterflies for both throttle bodies are mounted on one pivot bar that runs through both bodies.
The single, adjustable, mechanical "throttle stop" is only to keep the butterflies from damaging the throttle body bores at full close position. No adjustment is necessary if it's doing that one job OK.
There is one large brass air screw in each throttle body (visible above) for adjustment which is easily accessible from the left side of the bike. One and one-half turns out appears to be a decent starting point on the adjustment.
