And to Bazzaz rep - great way to get some customers by insulting them by agreeing with this moron. You know at least one guy who will not touch your product with a foot long pole.
Now you're taking what I said too seriously. Everywhere I go to look for bikes I get more "why don't you make a system for my bike" questions than volunteers for the model I'm looking for. If you disregard Kinetic's "idiots and moron" comment, which was probably just sarcasm anyways, than what he said was just very funny from my point of view.
Obviously I would like to make a system for every fuel injected bike ever made, especially Kawasakis because they're my personal favorite, but I gotta go one bike at a time. An the more bikes we cover the faster I can develop kits for other models because some harnesses and parameters will cross over between generations or even between models. We do have a kit for the ZX14, if we're lucky than that harness will fit the Concours. After I get everything done for the 10-12 I can bring the 08-09 in and hopefully that kit will translate over directly to the previous generation.
All that actuates the system is a solenoid valve controlled by the ECU. It is a "on" or "off" function that flows more oil into the VVT system. It can only run the cam full advanced or fully retarded, not constantly vary it in half-degree increments anywhere in between.
I never got the chance to learn about the VVT system when I was in school, but it sounds really similar to Honda's V-TEC system. Obviously it's not switching between 2 and 4 valves, but it's using oil pressure to vary the amount of incoming fuel mix and the speed at which it can escape. Except that I'm guessing on the Concourse the "engagement point" can actually be changed by the ECU, which is what makes it "Variable?"
