First off, I'm skipping the intro since I'm not new around here (AKA mrwhitepipes). I have alot of time invested in this bike and I want to use it as an example of what I can do, and also to asociate it with my bussiness, Antique Speed and Machine. I could not figure how to change my name, so I started off fresh. If anyone could help me with this, or is upset at the way I did it, please let me know.
I love hybrid engines. My favorite bike is the Harley DAH. I will never be able to afford one, so I figured I'd build this. I started collecting parts about 5 years ago, and after well over 5000 hours, it's finally complete. I view it as both my expression of what I think is cool, and for thoes who know their parts, its kind of a scavenger hunt to find all the details.
Theres alot to it, and instead of just listing what was done, I'll keep adding pictures and info as people chime in. I hope you all enjoy it!!!
Yes, it's all sporty parts on top. I wanted to run one of my vertical Wico's so that meant to carb had to go out the left side. I made new flanges for the cylinders and drilled through the fins so the studs use the head bolt pattern.
The rocker shafts are lubricated with grease. The linkage by the exhaust is the brake crossover. It connects the rod from the pedal to the shaft from the rear wheel.
The valvetrain is pretty simple. Andrews R5 cams and '48-'53 Panhead lifters. The lifters are taller than th 45" lifters. Th lifter blocks are machined to accecpt an oil seal in the tops to keep dirt out. I made little decorative cones that press on the lifters (just under the adjusters). The key is using the later Servicar cam cover. The sportster cams fit in alot easier.

I remeber your DL restoration, I met you at Lebanon Valley one time for their bike meet. Too bad that meet is dwindling down to nothing. I have a few friends in AHRMA, If only they could do a vintage flat track race there. Mabey it could be tied in with the Rhinebeck AMCA meet?
Its funny that you work with my brother. Our father works there too. You should stop by some time!!
Thanks to everyone for their responses. It's interesting what people pick up on and what they don't. No takers on the oil tank? I chose the wheels (they are actually pre-American Racing, note the internal, vertical rib on the spokes) due to all the aluminum I was using elsewhere. The brake drums have pressed on, aluminum cooling fin rings. I also used the fin look on the gas tank strip. I doubt the gas tanks need cooling any more than the brakes do, I just liked the look.
Yes, they were big chunks of 6061 to start with. I first turned the outsides of the brake drums (which was a big pain, the rear one is a re-pop and it was way off!!!) to figure out the finish ID of the rings. After I machined them, I textured them to look like they were sand cast. They were about .002"-.003" press fit. I have a major amount of pictures in the middle of the process missing due to a memory stick getting ruined.
The rockers are stock sportster. I replaced the bushings in them with bronze "T" bushings to provide a replaceable bearing surface with side-to-side wear. There are hardened washers between the rockers and the insides of the brackets. O-rings provide a little bit of a seal. The rockers pivot on tubes that are slightly longer than the rocker is wide. This way, when the through bolt it tightened down, it does not tighten on the rocker. Grease is supplied throught the bolt.
So how does it run? I think magnums are badass and I love the exposed rockers. I saw your post on the Dl that bike turn out great. I'm currently hunting parts for my 29 dl project. Great work!
To be honest, I have not started it up yet. I just finished it last week and I am trying to get some professional pictures of it first. Then I can scratch, spill gas and take stuff apart if it needs tweeking without it bothering me(too much)!!
