engine coolant heat reduction

I started a new thread on this because the original title was not in line with the topic.

As some of you know I've been fiddling with the cooling system to try to reduce the temp. For those of you who aren't familiar I've done the following. Added a third fan from a Duc 1098, installed a manual fan switch right off the battery which runs all three fans, coated the headers, insulated the heat exchanger and oil filter, added Muzzy blades to the stock fans, ducted the fans to get rid of the gap and improve airflow through the rad, opened up the bypass holes in the thermostat and filled it with engine ice.

The conditions-

Ambient temp 70F, fairings installed, engine idling.

Results-

Engine temp increase is a little slower than normal.
Turning the fans on manually at 165F maintains 165F. Doesn't get any hotter.
Three fans came on at 212F, temp drifted up to 214F and dropped rapidly to 195F at which point fans shut off. Did three cycles and all the same readings.
When fans shut off at 195F I turned them on with the switch. Temp dropped to 171F and would have continued to drop but it was enough for me.
On engine shut down ran fans for one minute and temp dropped to 147F.
Headers were warm but could be touched, fans were cold and the general area in front of the engine was just slightly warm. Took a side fairing off to check all that.

I'm pleased with the results. The fairings on made no difference in readings. It will no doubt be warmer on a 95 degree day but not by that much. 25 degree increase in air temp isn't going to drastically alter the cooling. So there. How ya' like them apples?

Results

I got mine. Boy do I ever got mine.

Way to go Lee. You have done great work. Many people have tried Muzzy fan blades, coating the headers, using engine ice or water wetter and all have had varying degrees of success. But nothing like what you experienced by adding a fan. Even if your bike doesn't over heat, but you just don't like the looks of it running at 220f and higher it sounds like adding another fan is the answer yielded the greatest results.

If I were you I would retitle the thread "the best fix yet for overheating"

Hopefully you will be offering this fix for sale for us bolt on and go folks?

Good work Lee, I always wondered why MV didn't put a third fan in there. Maybe due to the weight etc.

At least there is a possible fix for the 1000r and R312. My 1000s does not overheat with the simple mods that I've done.

Slow is smooth and smooth is fast!!

Good work Lee, do you have any pictures of the mounting of the third fan?
