1st attempt: Different eh ?
The parts were damaged to begin with, so I thought I'd play around.
The chain protector is designed, but not yet made. Pic of prototype to follow.
:D
Thanks POG
Looks great....I need a head like this. I had one spotted about 3 years ago and let it get away. Great looking engine.
Ron Carbaugh
Dear Ron.
Yeah I think the head turned out pretty decent for being #1. I learn as I go, and it will definetly improve, so I'll try another. These are full finned heads, and would go well with a custom downpipe. I also have a custom aluminum airbox planned for this package. :D
Thanks for your comments Ron. Always happy to do anything for you.

Rob,
It is neat to see you doing things like this that we did back in the early 1970's since we almost had to build all out hotrod parts from scratch. I have several modified side covers and some were done out of neccesity. Neat work.
Ron Carbaugh
That is so cool! I like hotrods and customs.

Trick head work! Very nice. Bravo! But, the 6 fin cylinder is what makes 'er fly?
And, I want one.

Rob,
Wow that looks so cool!!! Remember when you could send parts to "Yoshi" and have the heads painted a Red head or a Blonde? Am I losing it? No need to answer!!But what if you add color to the head?[:p]

Hey Rob,
Pretty sexy! But like any other cutie [:p], what's the other side look like? ;) You do some fine work my friend.
On another note, TC, his son and some other friends and I shared some fried shrimp at Gilligans Sat night, then topped it off with a ride in the forest Sun. Only got up to about 72 deg. [8D] Get on back down here sometimes.

Hi Rob, I was wondering if you would anticpate any noticeable vibration from your head mod? It looks very cool!
Great Job!!!! I wish I had the talent and vision to do something like this.

Bawb,
You are most definitely a machinist extrordanaire! How about working on a set of 35mm billet triple clamps for my KRP project in the near future? Mike

Excellent work Bob you are a true craftsman![^] This motor looks trick and fast![8D] Thanks for sharing,and keep up the good work!
Crash Carden, save a horse ride a Penton!;)
New model in black. Also the bottom fin is cut shallower, making a less radical transition between the cyl. and head. It's all fun.

Rob;
we had the same issue with the carb mount on our D engines. all the old manifolds were plastic and tended to leak air. The original for the bing was metal but also leaked. Cliff White machined the manifolds for our engines out of titanium. Very light very trick. I think its cheaper to go on Nutrisystems and lose the weight on the rider than to keep spending $ to lose the weight on the bike.
Bill Cappel
I should mention that the manifold was made to also redirect the fuel flow angle to a more efficient pattern also. In addition the manifold was matched the the intake ports.
Bill
I like it!!!:)
Sweeet! Rework of the intake looks very nice too!
