Well, it’s a high-strung bike, but over-heating on the street in comfortable temps (70F for example) is just NOT acceptable. I love the bike, but his is major issue. I’ve started work on trying to solve it. Here are some of the research points I’ve found, and lists of things that others have done.

This post will grow over time, and hopefully become a FINDABLE resource on the web, for the next owner of a gorgeous MV Agusta F4 1000R, that needs to solve this problem.

Here is a list of things another owner did, that I piked off of MVAGUSTA.NET:

MV Agusta . NET – 05-06-2010, 04:03 PM

• Installed Muzzy blades.
• Add 1098 fan to the left side of the upper rad.
• Modified the shrouds on the MV fans to eliminate the gap between the stock shrouds and the rads. — APR-15: it took me a week to decide how I wanted to attack this. In the end it was much simpler than I’d thought. – read about my experience here
• The fan switch circuit. All three fans come on with either the switch circuit or the ECU.
• Opened up the bypass holes in the thermostat.
  9-MAR. & 15-APR This seems like a simple thing to do to the thermo itself. My original plan t was to purchase a new thermostat to drill. In the end, I just modified the original by doubling the diameter the existing 6 bypass holes, which are extremely small due to the very narrow flange. Sorry, I don’t have any photos of this.
• Engine Ice — 15-APR: the instructions implied you need to flus the entire system to use the engine ice. Not knowing if any of these tips were working, I opted to simply use Water Wetter from Redline mixed with existing anti-freeze and distilled water. This seemed to help a bit, but didn’t seem to make a dramatic improvement.
• MV impeller
• Silicone hoses
• Coated the headers – having completed this modification, I’m unsure of how much benefit it really is, but I suspect there is some, considering the pipes are close enough to the cooling components to melt the original fasn! read about my experience, here

I ran the fans continuously below 40 mph. The important thing is to be able to get a jump on the temp before it gets up into the 200’s. It’s much easier to keep it cool than to have to bring it back down and keep it cool. On an average summer day, with the fairings on and the bike idling it would maintain 167F.

Hi-flow Bodywork

Another option found was to get these fairings with big openings to vent out the air. About $300 for the pair, and then of course I’ll need to get them painted too.. BUT it’s an option!

Updated Fairings from Catalyst Racing Composites:

Catalyst Racing Composites – 00-09 F4 Stock Left Side

Although they look rather garish on their own, once installed, I think it offers a decent accent:

Fan Shrouds

After opening the pipe, this is the view you get. From here, it was a matter of drilling out the center (drilled out a 2″ diameter with a 1 1/2 HP hammer drill), then hammering chisels along the sides to break up where it was attached to the inside of the section. The final step was using a 1/2″ drive 30″ extension to ram it out the cut-open end. This last part took a couple of hours, but eventually it was removed.

Final prep was a die grinder and grinding stones to the walls of removed section to clean up any remaining material. Inside there is a really BAD step section on the exit… and that’s something I was just not prepared for, nor did I deal with. It’s NOT ideal. If I’d known that was there I might have considered simply driving a new section of stainless THROUGH the core. But that might rattle, and I know that the way I did it, rattles are not going to happen. Once that was done, a good friend of mine put his TiG welding skills to use for me and sealed it back up.

Finally, the pipes were sent out for ceramic coating. That will be discussed in a separate section.

Pipes are back from coating! — see section on coating the pipes
