Re: Variable valve timing...how does this work? 900 1995

Varaible Valve Timing. Most carmakers have models with it nowadays.

Honda was one of the first to offer it in the late eighties. They call theirs VTEC. Toyota has VVTi. Our Alfa Spider has it. It looks rather simple. It's electomagnetically actuated on the intake cam. It kicks in at 3500RPMs...or is it 4500, been too long :o( Anyways, it gives a good boost in acceleration.

They're at the point now where they can continuosly vary the valve timing for whatever they like.

Variable compression...it's on it's way.
