I think a nice neat weld would not be a deal breaker for start up costs and time. Later when rolling could offer the machine piece as a option or if design was such that the billet machine piece could be added on to existing units sold already.

I would be down for one, PC black. agreed above with a clean weld, billet would be better but for cost and speed to market is important. I have the 120r and heat is always a concern as I get caught in a lot of stop and go traffic, hate to see the temps climb when stopped. Got a oil bud for when I am moving but pass 260 often when caught in traffic.
This is a great idea, would be glad to bolt it to my bike!

Looks interesting. I will give you that.
I had the lenale fan same one in fact on my last RG and current RGU. fan has been on the bikes about 75,000 still works well.
Your right air flow is only going to do so much it has a limit.
As for someone say fuel will cool it 25 degrees Not buying that been doing this to long.

Right now the front and rear fan housings are seperate sections with a short piece of tubing extending out the side, the center mount section bolts to the horn mount and the two fan housing tubes set screw into it at the same angle as the cylinders. I could build these with one section of tubing bent to get the angle with a mounting tab welded at the bend.

I also played with oil cooler fans, and while my fans did not fail from the bike environment, i.e., heat, vibration, etc., they did fail from road debris. When I took them apart I found little gravel like pebbles had found their way into the fan motors and bound them up. When I disassembled the fans and removed the road debris they worked fine again. Protecting the fans with a screen would probably solve the problem I found, but I simply opted to remove them. I may play around with them again at some point but I'm not sure.
Now as for cylinder head (or engine cooling) fans, whether the LeNale, fabrik8r's design, or any other, they are definitely a worthwhile pursuit. I will never remove the engine cooling fan from my bike, and if and when it ever fails, I will replace it immediately. From my experience and testing, there is no better bang-for-the-buck cooling methodology available. While oil coolers, and oil cooler fans do have their place, the engine cooling fans attack the heat at its source and minimizing that heat heat also has a relative effect on oil temperatures. If I were buying a new bike today, an engine cooling fan would be one of my first mods.

I must say that he's one of our ace problem-solving minds here and I always look forward to his suggestions. This thread is no exception, and is a subject that I've been interested in for some time.
