Lift the hood on a new 2006 fuel-injected Yamaha and youâ€™ll soon notice you canâ€™t quite gain easy access to the spark plugs. The Apex modelsâ€™ rider-forward ergonomics design required some changes in component location, so to get at the spark plugs some additional bodywork and components need to be removed to gain access to the spark plugs. It looks intimidating at first, but by following this list itâ€™s not all that bad.
1. Turn the two screws and remove the center shroud. These screws will stay in place within the shroud.
2. Remove the two self-tapping screws and chrome trim piece around the steering post.
3. Turn the four allen screws and remove the center dash panel (these allen screws will stay in place). The electrical connectors for the key switch and 12V accessory outlet need to be disconnected.
4. Remove two 6mm bolts and remove the headlight by moving it slightly to the rear, then up. The electrical connectors for the headlight and digital gauge will also need to be disconnected.
5. Remove one 6mm bolt that holds the smaller coolant tank in place, and move the tank to the side.
6. Remove the four bolts securing the plug caps. Each spark plug can be accessed using a swivel or flexible-type extension.
7. Reverse the procedure to reassemble.
