Honda cx 500 tech drawing?
(OP)
I got into a debate with some friends the other day, when I insisted that a cam-in-block & rocker arm system could live with a 10k redline in a production engine. My proof was the Honda CX 500. None of these whipper-snappers ever heard of it, and I can't find a technical drawing of any sort for this bike's valve train. Can anybody help me out? I'd love to win this argument.
Thanks!
Thanks!

Never heard of the CX500? Then they have no credibility. Funny how artists study and imitate the old masters before developing their own 'voice', yet young engineers seem delighted to reinvent the wheel rather than attend to groundbreaking historical designs, where the engineers had to rely on their imagination for development rather than fancy numerical modeling and CNC rapid prototyping . . . JMTCW. Whether it was 9K or 10K, the design was/is notoriously robust and eventually supported turbocharging as well as scaling to 650ccs.

I just can't find either a picture of the head without valve cover, or a cut-away drawing of the engine. The fiche pages show individual parts, but not a fully assembled valve train.

Anyway, why wouldn't you use a rocker at 10000 rpm? The inertia is a little higher than a direct acting cam, so you need higher spring rates, but on a design where you really don't want vertical height (width in this case) it makes sense to use a rocker.
