Paul! Fantastic illustration of the amount of creativity, stamina and skill required to reversely engineer an entire motorcycle - based on an 100 year old photo!!! Incredible!

This video made me think of LSR record holder Burt Munro and his determination to build a better Indian. He converted a side valve engine to an OHV configuration and created his own cylinders and heads modifying the cases and cams as he needed. Nothing but mad respect for your abilities Mr. Brodie. Keep up the good work! 🙂

[@rexschimmer7394]

Paul, the only word I can think of for this project is "staggering"! The amount of design work, and the way that you make your "drawings" in steel, then to get that concept turned into an aluminum casting and then make all of the tooling to be able to machine a part that has almost no parallel surfaces is a tribute to your creativity and tenacity! So impressive and a great lesson. Can't wait for the next vid.

[@chuckp8705]

It's impressive not knowing how to design a cylinder head, but then using creativity to start piecing one together. It's makes sense how it was done, but it's a good lesson to see and learn. Something to keep in mind on my future projects. There are good reasons to study and learn from others, but sometimes just diving in unencumbered by how it "should" be done or what rules and guidelines are out there allows a freedom to try new ideas. I admire people that can take the last approach and make it work. This effort really remind me of John Britten, and people like that.

[@cpdevon]

In my (limited but not so limited) experience with custom motorcycles, I can say that very few things impress me. You sir, have raised the bar. And it runs. You literally fab'd a motor out of "shapes" and it runs. Nobody I know aside from high end engine builders go to that level and it's usually built on known good values or parameters. You think out of the box. Hell, I bet you don't have a box!

[@dukecraig2402]

Believe it or not Porsche is who has been doing Harley's engineering work designing engine's for them since the mid 70's, some things like the finalizing of the ports and combustion chambers have been done by Jerry Branch at Branch Flowmetrics but Porsche has been the principal designer. In the mid 70's when AMF owned them Harley contracted Porsche to design a radical new engine for them called the Nova, when a new CEO took over AMF he canceled the project which was a real shame because a 120 HP production motorcycle in the late 70's would have set the world on fire and everyone else would have been playing catch up, but it was from the ashes of that canceled project that the Evo engine came from that was introduced in 1984 and basically saved the company, after that both the Twin Cam and the V-Rod were both Porsche contracted projects with once again the ports and combustion chambers finalized by Jerry Branch. That's one of Harley's best kept secrets with them covering it up by saying things like "When OUR engineers sat down to...", yea, their contracted engineers in Stuttgart.

[@Arthagnou]

Super Ballzy, you should put some valve covers on the head. 2 reasons 1) you could actually sell these for other hotrodders to put on their one custom bike (total loss oiling, really doesnt sell well thee days) 2) Make money!!! then do (or sponsor) more cool things. I always wanted to modernize a Duesenberg engine( a DOHC, 4500rpm limit with 7:1cr leaves alot of room to improve)....you have actually come the closest to that dream. Bravo!!!!

[@paulbrodie]

1) these engines have a recirculating oil system. Where did you get the idea they are total loss? 2) There is so much work that goes into these motors there is no way to make $ selling them. But thanks for watching and commenting.
