I enjoyed the read. If you want to get into an oil war, go on a v-twin site and just mention oil change or synthetic vs Dino oil. Grab some popcorn and watch the posts. These v-twins run hot. It is the nature of the beast and it doesn't surprise the engineers that designed them. However, sitting in traffic they get upset with heat and start doing all kinds of fun things! With that being said, I am only concerned about traffic situations. I know that if I.am going to do a toy run or parade ride, I take a bike with a radiator! I have read somewhere, about oil viscosity break down and the temperature where that occurs. It has been some time ago but I am thinking that doesn't start to occur until 275 degrees and up, and that was with regular Dino oil not this new synthetic oil on the market. Most of these big displacement v-twins come with oil coolers installed on the bikes now, if there is no water cooling. I guess I said all that to say this, I just want some cooling happening when I am stuck where I can't get air across the engine. Are you saying that the fan blowing on the cylinders is sufficient for cooling in stop and go city driving? I am just trying to figure it out since I do not have a temp gauge on the car

Yes, the Urban fan is for Urban driving and only comes on if M3W is below 12mph or stopped and yes it does cool the back of the jugs as it pulls air in from the sides.
