I dunno. I was talking to Yoshi a few weeks ago and he said he had one but it looks like it might have been owned by Kiyo. Serious commitment to build with that one, IF anyone is actually gonna use it!

Scan it and set up the CNC. Gotta keep one clean copy. Awful pricey for the typical SOHC4 dude though. A machinist would be a good home.

 Had a breif conversation one day with a fellow in Vancouver that had on of these on his sandcast 750, back around 70 or 71.

I did some research on these heads some 20 years ago and like Frank, the trail led me to this guy in Vancouver where it went cold.
I can't remember any of the details from back then and I even contacted Piper who couldn't come up with any details.
Piper Cams are still trading from Kent in Southern England, here's a link to their address.

LMMFAO Leroy.

Somebody (Keith) get one and turn Maestro Mikey loose on it (after his chicken wing heals). Can't imagine what he could do with this! Then Leroy could CNC them  ;)

At least these comedians are calling your busted wing a turkey leg or turkey wing...could have been worse.  I broke the ball  off of the ball socket in my left shoulder.  So,if your surgeon suggests surgery for repair to soft tissue damage do not think twice about it.  In the long run you will be ahead.  The shoulder is the most complex joint in your body.  Find the best shoulder specialist you can, it is not an easy thing to fix properly. It is a very specialized set of skills. You should appreciate this knowing what you do about head porting.  Not just anyone with a flow bench and cutters can do magical things in performance.  Same applies for your shoulder and it healing with the fewest complications.  Do not ignore your doctor's and therapists advice Mike.  You will heal faster following their experienced wisdom.

That is an incredible piece of engineering in that head.  I wonder how much difference it would make and driving four valves instead of two adds to the head's friction and requires the oiling system to be top notch.  Wonder if a twist on the design with roller rockers could net even more improvements?

Wow Mike, I only just got to hear about your mishap, I hope the damage is nothing to serious and that you recover quite quickly.

Are bucket style valve actuation a superior design or one of fewer parts and more direct actuation of the valves?  Is it also a mechanical advantage of not having something like a rocker arm transferring a force through a pivot point?

Definitely superior to full rockers. The buckets are tending to be replaced by follower arms over the last few years. Or a combination of both with a SOHC.

I considered buying this when it was first listed but decided the money would be better "invested" in other areas on my Automatic dragbike.

Sure looks like Piper may have been the company who "exclusively designed and manufactured" this head for MTC.
