City Driving and Engine Temps
I see posts on here where guys say they run 230 degrees and lower even in the middle of the summer. That can't be city driving.
I was out today 70+ degrees and just driving around town a lot of stop and go. I'm running straight Dino in my 103 with 1K miles and I was getting a reading of 245. On the highway, I'm below 220. I had the bike tuned by a reputable tuner.
Also do you guys always keep your Engine Temp Mgmt System on, or do you disable it?

When sitting at a light, I roll my throttle forward to get cooling air pumping through the motor.
I use syn 3 HD oil
I don't have a "tuner" but use nightrider XIEDS which can contribute to cooler running
oil cooler always helps

I don't have an oil temp gauge but I seriously doubt that my oil temp is anywhere close to 245 in the summer time in the city, or the highway for matter. It's probably a lot higher than that. Stock engine with
I always keep my EIMTS turned on, and it kicks in all the time during the summer. Kicked in several times Saturday.

Personally, I believe the parade fan is the best insurance you can buy to prevent excessive engine temperatures in city traffic.
Here's a link to some actual testing I performed with a parade fan...

I'm about 235 in 88 degree weather on the highway (i95 in N. Va traffic stops and goes) - EITMS always on. I agree with 2black1s, I installed a HD parade fan a week ago and the EITMS has not activated since - including about an hour in traffic due to an accident this morning. For me I think it is the solution I needed.
BTW, thanks 2black1s, I purchased The fan after reading your parade fan threads.

Bikes never entered EITMS creeping along for 1 hour in the low 90's with the fans on. Even after stopped for 1 full minute... Just to test I turned my fan off and 3 minutes later....one cylinder. Turned the fan back on and after about 5 minutes or so, back to two cylinders.
THANKS 2black1s!

Recently made some interesting temperature observations myself. I finally finished my temp monitoring system last week when I added the front and rear CHT, with a small rotary switch, I now have the capability to toggle through temps; oil supply from pan, cooler in, cooler out, return to pan , front CHT, and rear CHT. There is absolutely no reason to have this type of monitoring system except I'm trying to capture actual data to quantify the effectiveness of my cooling system prototype. Anyway, my tune condition is lean like stock so my observations can be associated to the temps experienced on a stock bike. Weather conditions 85F and sunny. "Normal" highway cruising within 7-10 min riding, my rear CHT normalizes to 280F, while the front CHT is typically 20-30F cooler when traveling. After stopping for just a minute or two, the front will catch up and they will both jump up over 300F. Ran into some dead stop and roll construction traffic, within 4-5 minutes my rear and front was 340F. My bike is an 06 so it doesn't have EITMS. These temps I experienced were in conjunction with a very effective fan assisted oil cooler. Before the mods and the ability to monitor temps accurately, I know my bike was running way hotter than it is now. At least now I know just exactly how hot. Just for general info, it only takes about three minutes of idle from a cold start (first start of the day) to break the ECM "warmed up" temp of 167F. BTW my oil temp never went over 205F today. Some of my previous assumptions about the relationship between oil temp and CHT are no longer relevant, but now I can draw new conclusions, not just assumptions. Have fun digesting the new info.
