Just wanted to give props to Jason for making such an excellent product. Where I live I have to put up with lot of city traffic. These fans make a HUGE difference, now the motor never gets hot enough to go into EITMS mode, even in traffic jams. The bike is much more enjoyable to ride in hot weather or heavy traffic. Very pleased and can't recommend them enough.

Same manufacturer, and the low power fans are in stock at several suppliers. The bump up in fan output was not that remarkable, but the bump in performance changed everything, it pushed my system into a class by itself. I can't go back now. I'm going through the process of trying to find a new source for fans, it is very slow and aggrivating, manufacturers offer me everything except what I ask for.
I guess you lost me? Bump in fan output not remarkable but bump in performance changed everything? Whats the difference? Sorry for the stupid question.

So as of this posting, what is available, how much and how long from order to delivery?
Are the larger fans I see in your pics now available?
I read what you said about being better at operating speeds and not much improvement at idle, but I assume still an improvement if I read that right.
I am 100%very interested, this seems like a no brainer.
I really think with a little more r&d and real world applications you could have come up with a mod all Harley makers will want to incorporate as a fix for over heating motors and there are no shortage of those, congratulations!!
I like the look of the larger units as much as the idea of them cooling my heads, all in all a winner for me, now, how can I get this?
Anyway how much, how quickly and have you a pic of the latest version of this unit.
Thanks

Lump,
I just replied to your email. HDF member price for a basic black and stainless system is $250, finish options and switch is extra. As of now I have no fans for new FCS orders. This thing with my fan order not being delivered totally screwed me, and everyone currently with deposits waiting on their systems. The static improvement was negligible, like 2-3 degrees, which to me is really not worthy of mention, although technically it was a slight improvement. I'm sorry but there is no way I can publish an estimated ship date given these circumstances. My sig pic is not current, but the only difference is the connector arm angles are corrected to match the angle of the cylinder fins.

Not a stupid question, and one that deserves an explanation since my comment was unclear. When I stepped up to a slightly more powerful fan, there was not a significant improvement in cooling potential in a static or slow speed operation condition. What it did was increase the traveling speed the system will provide cooling. With the new fans it provides a substantial cooling benefit up to normal highway speeds, for me that was 30 degrees drop in FCHT on my bike at 80 MPH compared to without the fans, more on the rear head. I only tested up to 80 MPH, because the cruise control won't lock at 90, so I use 80 as my reference speed, which should cover a majority of riders operating at normal highway speed. So now the system is set apart from all other cooling systems because it is a full time cooling system not just for slow speed, "parade" duty, or when you get caught in traffic; this system keeps your engine significantly cooler the entire time its running. The increase in fan power was very small, compared to the gained performance benefit of cooling at highway speed. It was an error on my part early on in development because I was not looking at cooling full time across the full spectrum of operational speeds; I was under the impresion the engine would achieve full cooling potential from natural airflow at traveling speeds. When I initially tested different powered fans I did not observe a great improvement in performance with more powerful fans, but I was only looking at static operation. Now after conducting dynamic testing at normal riding speeds, the slightly more powerful fan makes a big difference in cooling while in motion, but still doesn't improve much while sitting still. Overall the system is relatively low power, output and consumption, but it is very high efficiency, and its cooling performance is exceptional. I have some new developments on the horizon but I don’t want to reveal them until I'm positive I can make it happen, but I am still trying to improve the system a little more. I’m striving to provide the best system possible.
I really appreciate you taking the time to offer that explanation Jason. I'm still tickled pink with my original fan. Works well for me and the addition of an oil cooler should help cover the highway oil temp. I may have to look into purchasing one of the upgraded fan units in the future to help reduce the head temps at highway speed but for now, I'm happy with what I have. Thanks, Rick

Chrome Preview
Got the first batch back from the chrome shop, now if I just had enough fans to assemble them all. . As promised I kept enough fans to fill the original chrome oders and I shipped 4 yesterday, waiting on a couple more invoices to come back. Newer chrome orders will not ship until I get more fans. The latest update from supplier is I should have fans by mid Nov. Trust me folks this is not what I had in mind, but I learned how to prevent this delay in the future. I'm hoping this next season will be much better for customers, with a much quicker turn around time. The final cost came in below my original estimate so the chrome option will be an extra $60.00. I put black screens in one to see how it would look, not bad.
