Bill, that's a sweet ride!

That puts the Boss Hog to shame! I would have loved to have seen one of those at Sturgis, I'm sure it would draw the biggest crowd there.

Very interesting torqure converter, just love things like that.

Like Ol'Ron, I just love things like that. Also love people like Boscobill. They don't run into problems, they run into opportunities. The opportunity to prove that it can be done and that they can do it. This build makes some of my problems/opportunities seem pretty trivial.

Way to go Bill!!!

Amazing engineering! Where there is the will there is the way. Especially with your talent.

Re: 37 Flathead V8 bike project
 

Very nice, how about more info on torque converter.

Re: 37 Flathead V8 bike project
 

Wow thats using your head for something other than a hat rack!! Nice job!

Gee, Thanks guys, i build cycles to ride, not really to show or sell. I had always dreamed of having an Indian 4, but realized i'm getting older, and the chances of that ever coming about were slim. The flathead V8 was the only substitute. Most of the ones i saw online used the extremely hard to find V8 60s, or were monsterously misproportioned. They also all were using a single speed right angle gearbox and stock clutch, and were said to be a bit impractical for a daily rider, and a handful to start out, especially uphill. My soulution was to use the torque convertor and front cover/pump from a Dodge omni. I used a 12" saw blade to adapt it to the V8 flywheel,
utilizing the original pressure plate bolt holes. Also used the Dodge's front clutch after cutting the planetary hub off of it. I shortened the drive shell and welded it to a stub pto shaft, driving a short chain turning a goldwing 1500 shaft drive rear end. The case was made from 9"x1/4" steel tube counterbored for the pump/cover and rear bearing cover. Using cardboard templates, i laid out the steel bellhousing and welded it up after truing. I routed the pump output to the converter with a relief valve from a yamaha, and ran pressure to the clutch via an external ball valve ,allowing for neutral. The stall speed matches the V8 well, smooth solid take offs, and acceleration up to 95+. The old flatty is being fed by a side-draft S&S Super G, and runs smooth and strong. It has proven to be a hassle free daily rider, and a true joy to ride!

I'm impressed! I am very impressed! You are some grease monkey. I'd love to see it in person, see you ride it and hear it in real life. You are amazing!

Re: 37 Flathead V8 bike project
 

I'm very impressed, engineering and imagination, congratulations on a superb effort.

Re: 37 Flathead V8 bike project
 

Since the last time i posted , have upgraded to a lock-up style converter and built a gear drive to replace the chain from trans to driveshaft and committed to a color....Also added a GM hei distributor as an ignition trigger, driven from the crank by a small timing belt, as this makes adjusting the timing a breeze, with centrifigal advance as well as the vacuum advance. The timing cover distributor still is used for spark distribution an the points are still there as a backup if the hei module fails.....http://sphotos.xx.fbcdn.net/hphotos-...31713137_n.jpg

boscobill you are a very taltened man

Re: 37 Flathead V8 bike project
 

This bike is really sweet - have you posted this over on the HAMB, BTW? I think the folks there would get a real kick out of this build .... way to go!

Re: 37 Flathead V8 bike project
 

Very nice! Something like this really interests me. Would love to see it someday and meet you.

Hats off to Boscobel Bill and the Flathead V8 Bike project. it deserves a place of honor among the other great bikes to come out of Wisconsin, or anywhere else for that matter.

Re: 37 Flathead V8 bike project
 

Wow! Amazing. That's the best flattie bike I've ever seen. How does it handle and steer?

Re: 37 Flathead V8 bike project
 

Nice!!! I like it!

Sent you a PM as part of the great promote v-8 60 project. Lou
