Hmm can't say that I've ever seen one, I'll google it in a secont. And I have a prety good idea on how to set up a cooling system.

I did a search of my own and first made the mistake that I found nimbus on Wikipedia and it was a helicopter jet engine. I suspect someone will put one on a motorcycle!
Interesting though is that the engine had disc brakes to slow the blades when encountering high winds, I guess or they might break off?

Next with a picture I saw what you were referring to.

I also had seen in some TV news, Zenvo ST-1, a car that costs 1.8 million dollars and has 1,104 HP using a turbo and supercharger. Come on find a way to put one on a motor bike!

BUMP!!!! This is too nice of a bike and deserves to be closer to the top...... What's next? Are you still considering a 20's Indian?
Yes...the guy who wanted me to do the Indian has had a change of employment and asked me to put it on the back burner for now, but I'm going to go ahead with it anyhow. Got an engine, a donor frame and wheels and been experimenting with some 'different' ideas. Probably start sometime in the new year after I get done with a couple of motorcycle restorations. I'll start a new thread for it when I do.
Merry Christmas and Happy Holidays to all! Here's to a good 2012!

It's Orange-Cream Sickle-Licious! What a good looking bike. Need to get old time clothing for rides now!
There is a pawl bolted to the clutch hub that catches via a very light spring in a notched band that is fastened to to drum. When not running, the spring pushes the pawl into contact with the notched band; when running centrifugal force overcomes the spring and the pawl disengages. There is a small steel counter weight welded to the opposite side of the hub to keep it in balance. If you are patient with me I'll post a drawing later.
Here you go, I hope it's of some use.
The band might not be necessary if your clutch drum sticks out past the hub far enough (about 1/8")
There was a hole already in my clutch hub that I simply tapped 1/4 UNF to fit the pawl screw...upon final installation, I peened the end of the screw over to prevent it from unscrewing and falling out. The roll pin prevents the heavy side of the pawl from contacting the drum when running and also provides a point to fasten the return spring. I use a rare earth magnet to hold the pawl in the disengaged position when pedaling , or pushing it around. Also the heavy end of the pawl rests on the central part of the clutch hub when in the engaged position, I figured this would give it some extra strength and take some of the strain off the drum.

Thanks Goldy for the clutch pawl idea. That will go perfectly with my compression release you made. If we trade enough ideas, our machines will just get better. Great job.
I suppose I should wait for msrfan to respond to this question, but since there is a nice little hole in a similar location for the governor shaft I suppose with a little care and luck it ought to work just as well ????
