feelergaugephil,
Not to nit pick, as I don't want to discourage your enthusiasm to offer help and suggestions (or anyone else), but there were a few inaccuracies in the information you provided.
The C14 has solid cam gears, so using zip ties to hold the cam chain to the gears doesn't work so well, unless you have something else in mind (please elaborate if so).
The lower cover uses a o-ring, so no gasket worries there. It appears the factory put some additional sealant (Hylomar perhaps) on that cover too, so one might consider doing the same.
As for removing the fuel tank, it does nothing to help with access to the valves on the C14. The fuel tank is nowhere near the work area. Also, the frame above the throttle bodies and valve cover is one piece, completely blocking access from above.
Other than that, great info. Thanks!
