2006 VFR Overheat Problem

[John Rupinski]

I run my VFR from 6,500 to 10,000 RPM on twisty mountain roads and I'm consistently above 210 degrees even as hot as 245. I have 1 fan and it comes on as it should at 207. Is there anything I can do to get my machine to run cooler other than running engine ice for coolant which I already do. How about a second fan, aftermarket oil cooler, or higher pressure radiator cap? Anyone else have the same problem?

normal for 6th gen
I put switch on my fan and just turn it on when I ride that hard has not gone over 205 as of yet.

My O6 runs hot in similar temperature ranges you describe. Air flow is everything and it usually doesn't go above 230 unless I come to a stop or slow way down. I have noticed the higher rpms do generate more heat. My son has a CBR600 and picked my VFR up after I had new tires put on it. The outside temp was around 105 and he kept the rpms up fairly high just under vtec. The temp got up to the point where the warning light came on.

I wouldn't worry to much. Your temps are right in spec. I take mountain rides in 50 and 60 degree weather all the time, and if I'm riding even remotely hard 220 degrees on the gauge is common.
I get that same 220 even if it's 90 degrees outside.

I ride a 2007 VFR 800A. Here's my suggestion...

Unless you've been having any actual cooling problems, switch the digital temperature meter display from 'coolant' to 'air temperature', and then forget about it. Doing so will free you from the habit of distracting yourself, fixating on, and fussing over this meter. Instead, just ride the bike and enjoy yourself.

When the temperature meter is set to read 'air temperature', it will automatically begin displaying and flashing the coolant temperature if it ever rises to 251 F, or 122 C. At the same time, the 'high coolant temperature indicator' will light. Unless this occurs, forget about it and enjoy the ride.

I've rode the piss out of my bike in 100 degree, high-humidity weather, with frequent idling at stop lights, traffic jams, etc, and I've yet to have a problem with the bike overheating. If I'm caught in a long traffic jam and I can't hardly move forward for a while, I'll shut the engine down and relax until I can get moving again. YMMV.
