I can’t believe I am about to post this, but I am looking for a used softail! Yes, it is a bit embarrassing. I know I doesn’t sound like typical e-fab stuff, but I need that counter-balanced twinky for this concept I have been kicking around in my head. So if anyone has (or knows someone who has) a twin cam softail for sale, please let me know. Obviously I am not going to spend much, so please don’t contact me with the “I put rhineharts, a tuner and apes on it” routine please. Preferably one with the grey motor. Obviously clean title too. 203 315 9908

I did an interview a few days ago with a guy from Barnetts magazine. He asked me a ton of questions about the new bike, mostly asking me why the tank looked so cock-like, and put together what is probably the most homo-erotic bike story ever. Well, hopefully there is no such thing as bad press! check it out-
I know I have been all over the map with blog postings recently. Mostly it is because I don’t want to give away what I am working on untill Sturgis! In the mean time, here is a good one. In my obsession with aircraft engines and all their various configurations, I came across this. It is called a Turbo Compound. This was yet another WWII era concept for boosting piston engine performance, similar to a supercharger or turbocharger. In this case, spent exhaust gasses are routed around the crankshaft of the engine. The idea is that the fast-moving gasses actually help turn the crank itself, rather than an air compressor to re-feed the intake. A main reason why this was explored as an option was because, unlike conventional forced induction, it does not increase fuel consumption, but still increases power. These systems are also known as “blowdown turbines”, because they take specific advantage of the fast-moving exhaust gasses created by the piston moving down on its power stroke. This is possible by having the exhaust valve open before bottom dead center on that stroke, allowing explosive combustion gas to escape early. Get it? Give a little here and gain a little there. Amazing. Obviously I am wondering if this would be a viable way to increase power on a motorcycle. Apparently these engines (at least in aircraft form) were not vary popular, as the advent of turboprops and jet engines took over. However, detroit diesel apparently made an engine with one in 2001. ok, here are some pics:
This one is in a radial aircraft engine.
Apparently a few found their way into the later versions of the Lockheed constellation. Howard Hughes was partially responsible for this aircrafts development. (as seen in the movie “The Aviator”)
Apparently, turbo compounds were hated by mechanics because the exhaust valves got the shit beat out of them and needed frequent replacement. It does make sense, if the valve is opening early on the power stroke to increase exhaust manifold pressure, it is going to get a lot hotter. Maybe it isn’t such a good idea to try to adapt this one to bike. It is hard enough to keep a regular Harley running right!
This is something I made a while back. It is for a 4 speed style clutch, but i can make one for any type of belt drive as long as I have an original to get dimensions off of. Oh, and if you guys are reading this- send the damn thing back to me! If I see it on your bike I will re-claim it on the spot…
Well we got home Sunday night after 3 days of hanging out at the worlds oldest bike rally. These days it seems like the worlds oldest people have taken it over though. It is a shame that Laconia has become so bagger/geriatric oriented, because it is an absolutely beautiful place. My hope was that more of the Limpnikie Lot would show up, but it seems like everyone is too exited about the smokeout next weekend. Certainly if the whole lot actually showed up we could have ruled the whole rally, but it didn’t happen. A few good things though, we didn’t have to pay anyone to set up- awesome! Good thing too because we only sold a few things and if the town goons had raped us like usual it would have been a total bust. We also got to see our friends Leslie, Venom Mike and his crew who have access to a sweet house a few miles from Laconia where we could drink, set off fireworks and catch up. We also got to visit Acme Choppers which was great as usual. Their shop is an inspiration to me- so professional and well equipped. They were even cool enough to give me a frame jig they werent using! Amazing.. I’ll post some pics when I get it all set up here. And the best part happened Sat mid day. We were all standing around the Limpnikie rig (basically an 18 wheeler) when all of a sudden there was a huge boom and the whole rig literally hopped up in the air and moved about 3 feet! We ran around and found that a huge tow truck had rammed the front of our truck! This was a big, heavy tow truck too. Anyway.. chaos ensues as a guy opens the passenger side door and slumps out of the cab with a huge gash in his head, and the driver just stays in the cab with a dazed look on his face. After all the cops and EMT people take the two guys away we finally get the low down. Apparently the guys engine stalled about 50 feet away (up hill from us) and the rig just started rolling backwards down the hill. He claimed that when the engine isn’t running the brakes are completely useless and there was nothing he could do (?). On the way down the hill he also side swiped a little car and smashed the shit out of my friend Mikes minivan -with him in it, before hitting our rig. Luckily Mike seemed ok and hopped out and began snapping pics of the whole thing (He is arguably the most famous motorcycle photographer ever by the way, www.lichterphoto.com ). Amazingly no one on foot was in the path of this thing when it came down the hill because they would have been squashed into pizza for sure. Anyway, the riding up there is truly amazing and even though I was by myself I had fun just cruising around the lakes and through the fields soaking up the sun (when it wasnt raining). Ok that’s all for now- back to bike building to get ready for Sturgis! -L
Laconia is coming up fast. Efab will be set up at the “Lobster Pound” area off the main drag. We will only be there thurs-sunday. If you are in the area please come by and check out the bikes. I will have “Interceptor”, “Daddy go Hard”, “Flash in the Pan”, and a brand new one..still un-named. All are for sale except Flash.
Decided I would try 01 tool steel for my cam. I see no reason why it wouldn’t work. I took measurements off of the existing cam (which does have correct lobe profiles, just incorrect front cylinder timing) and got an overall diameter of the lobe area. I also pressed the drive gear off of it so it would be easier to measure. What I am doing now is duplicating every part of it that is symmetrical on my lathe. The only other things will be shaping the individual lobe profiles and heat treating it. Here are some pics:
Messed up cam with gear removed.
Messed up cam next to my bar stock for new cam.
coming along…. tool steel mills slow and hot..
Turned around in the lathe to get the other end. 4 lobe “blanks” done!
