When you pull in clutch you lose gear indication. You can read all 6 gears with power vision and harley has a all gear indicator that mounts on the handle bar so the signal is there. I am not sure gear control is the best option shifting and running through the gears spiritedly once and a while. I tested yesterday and you can get cooling at 60 mph. just like Jason said and with cams many can run that in 6th. Anybody who has tried to do process control knows this has the potential to be really annoying if the fans get caught up in a off, on, off, on situation 10 times in 10 seconds. This can get very complex or very simple really only need on at x temp off, on at x speed, temp with a delay so they dont get in a quick off, on state.

RKC Install?
Anyone out there with a RK or RKC installed these fans yet? I'm just looking for some advice on where to connect the power to have it run off of accessory. Hooking it up to the battery allows it to be turned on anytime, and I don't want to take that chance! Thanks!

Ok, So this evening after the day got much warmer 85F and I had come off an hours interstate ride, then 55 MPH for 32 miles on RT 15 and finally on to the 6 miles of uphill gravel road traveling in mostly 1st gear to my house my oil temp ended up being 225F when I pulled into the garage. Again a far cry from the 240-250F I usually see on this run and on much cooler days than today. I still think that I am going to purchase and run an oil cooler as well....Any further help in reducing temps is a good thing! The fans however have sure given me reduced temperatures and peace of mind. I'm also not sure just how accurate the Harley digital gauge is....But in any event I'm sure its good enough to read a drop in temperature...which it did. Also, as the crowd gathered at the local dealer to look at what was hanging off the side of my bike, I did manage to get into a debate with a local engine builder...Kind of a Know it All guy, but admittedly a good engine builder, who challenged the reduction in oil temps. He gave every conceivable reason why it cannot work to reduce oil temps. Fact is it does because I witnessed it! He asked me to prove it by bringing my bike to his shop to run on his Dyno and look at the temps. I don't run my bike on Dynos, but he insisted that he would only run through the gears and won't be beating on the bike. With fans off and then with fans on. I'm still not keen on running my bike on a dyno....But I'm thinking about it?

Its encouraging to see that you got very similar results. Also as iclick has identified the fans will halt or drastically retard the gradual temp increase. So when you combine those two characteristics and you activate the fans as soon as you drop below that 60mark, the engine just won't reach those 300+ temps and IETMS is a thing of the past. When you come off the highway and your ET is say 250F you can keep it there. So static testing doesn't provide a realistic representation of actual operation, if you let the engine get up around 300F or higher while sitting still and then turn on the fans, ET won't drop as cool as it would if the fans were switched on earlier befor it got that hot. Point being quite simply turn the fans on as frequently and early as possible for maximum cooling benefit.

Rick - The laws of Thermodynamics dictate how materials react to heat. Not sure where Your "Engine Builders" logic is but a cooler engine means less heat which has to translate into lower temperatures (including the Oil). I think I remember that from a College Thermo class.
Now I do agree that at some point both Engine Temp and Oil temperature will stabilize and they will likely be very close but the only time the Oil Temperature could be higher than the Engine Temp is when the Engine starts to cool off and the oil has not yet seen those lower Engine Temperatures.
A good example would be when you shut you engine off. The Engine cools rapidly but the oil cools much slower and could be warmer than the engine.
I think his logic (if he has any) is slightly flawed ( but then I'm only a registered Professional Engineer so what do I know?) LOL.

Short answer I'm pretty much on track with the original estimates I gave folks. I'm releasing a few for the third batch tonight, should have the rest of the third batch done next weekend. I am now getting all of my housing components done by CNC, last week I ordered enough parts to build 250 sets, soon as I have them in my possession I plan on taking leave for a couple weeks and getting out of this back order situation. Within 6 weeks I should have all current waiting lists taken care of and have some stockage to sell on the website finally.

Leg heat
I installed the LaNelle fan before I heard about this effort, and yesterday was the first time it was put to test, and I have to say that my right leg got really hot from the fan air blowing through the head.
My question is how is the leg heat on those who have crawled along in rush hour traffic on a hot day for 40 minutes or more with the Wardspartswerks fan????

His attitude in General is slightly Flawed! LoL. He builds a very fine motor, but he has lost more business because of his less than bubbly personality! I have proven to myself it works and your response and qualifications reinforces my opinion. Thanks
