Adjustable Cam Gears

[Blackduck]

Does anyone now if there are adjustable cam gears available for the Valkyrie?
Thanks Blackduck

Nope, there was some talk about that many years ago,but, it didn't come to anything.. Wouldn't make too much difference anyway..

Someone, I don't remember who, figured out that you can press the cam pulley apart and clock it, and it will advance your valve timing. I think it was 4 degrees.
But the adjustable pulley didn't show enough interest to warrant making any.

on the dyno. We weren't very informed in cam degreeing so someone who knows what their doing may have better luck. I had a local machine shop build mine using the stock gear as a pattern. My personal thought is that the timing belt allows so much variance in cam timing that you can't get a idea if you are gaining or losing HP.

Thanks for the replies. Looks like it will be some old school aligning.
Cheers Blackduck

Wow!!  This is amazing!!

I just clicked on here to find out about this because the '99 Standard I just bought supposily had this done years ago.  Or at least that is what the seller told me.  I'll see what I can find out when I pick this thing up tomorrow. I don't think this guy did it himself and I'm not sure if he would know exactly what was done. From my old hotrod days usually when you modify something to run quicker/faster you eliminate the longivity.  If this is the case I'd like to go back to factory.

I bought this one for traveling on longer trips and I'd like it to last, right now I have a C50 Suzuki (a good bike but a bit small for this with two-up).

I would think changing the cam gearing/timing would be a REAL bad idea. Wouldn't the pistons and valves collide (at least once)?

You don't change the "gearing" you just change the timing. So the valves would open a little sooner. I believe the only thing it will do for you is move the torque curve.

Jeff is right, you are changing when the valves open and close in relationship to the crankshaft. Incorrectly setup and you bend valves.
What I have is the right cam is 1/2-3/4 tooth advanced, not a lot in the real world but I would prefer to to be correct. About 8 degrees of crankshaft rotation
