I monitor my oil temp at the swingarm pretty closely. It was in the 90's yesterday and I noticed that the oil was right at 200 F +/- a couple degrees when I would check it. My fan only comes on at shutdown (so far) since fully installing the comfort kit. This seems 5 or 10 degrees hotter than what I remember Before Comfort Kit ( BCK ). I also remember the Buell engineers always claiming that a RSS would keep the fan from coming on but the rear head would be hotter. Anytime BCK the fan would come on if the oil got over 195 F at the swingarm. Not these days. I'm not complaining, just observing. My bike runs like a top, always has. I kind of wish I could turn that fan on with a switch so I could see what effect that would have on my swingarm oil temp. But anyways, so long as that oil temp stabilizes (like it does) I've got no worries. I think one of the reasons my bike always has run so well is because I rarely clean the thing. The most I do is wipe it off and even that isn't too often. Sometimes I wish I were more of a neat freak but then I'd probably be bitching about corroded 77 connectors and hard to figure out electrical gremlins. My bike is like the dirty kid that never gets sick. | ||

EG- You could accomplish your experiment as follows: ride a steady pace at a speed that you know won't cause the fan to kick on and monitor oil temp. Pull over and stop with the motor idling long enough for the fan to kick on. Then repeat test at same speed with fan running and monitor oil temperature until it re-stabilizes. That should give you the comparison you're looking for. | ||

Considering that all heated air, from rear cylinder, is directed at the swing arm/oil tank with the comfort kit. I don't find the observation surprising. | ||

Electraglider, The switch to turn on the fan is speed. Any speed > 15MPH and the fan is on once the engine warms up. So, unless you are stuck in traffic, or climbing goat trails, the fan is running with the comfort kit flash. | ||

Windrider- his Uly is a 2006 model; there's no updated flash available for the 2006 or 2007 models. | ||

I have pondered this exact issue with my 06. How can I get the fan to come on anytime I am moving, in lets say, low speed mode, since as has been noticed before, the fan blade is a restriction to air flow when not spinning. I have a couple ideas, seeing as how the fan is always powered, just gets a switched ground from the ECM that switches slowly for low speed, and faster for high speed. I could build a switched circuit with a relay system so as not to feed ground back to the ecm. Hmmmmmmm Bruce | ||

Rr_eater, I've been thinking of the same thing, I have an 06. But I'm sort of lazy, and I'll eventually get to. If you beat me to it, please post results/how-to. I was thinking about some type of rheostat control, but I haven't done any further looking into this. | ||

The primary trick to this is disconnecting the ECM from the circuit while utilizing it, at the same time letting the ECM control normal operation, that is the catch for me right now. Bruce | ||

Instead of bypassing the fan, would the mounting of a second fan wired as such be a potential solution? I know very well how limited space is in this area, however you could stack the fans (pending clearance) and the added air pressure would definitely keep the blades on either moving when the other is in operation. I would think that matching RPMs or output on a two-fans-stacked setup might need to be considered. (Message edited by methed on June 07, 2010) | ||

Methed, I like the idea but I don't think there is enough room. When I did my O2 sensor things are real tight. Rr_eater, I need to get with my more advanced electrician friends and see if there is a sort of disconnect that we could put in the harness to take the ECM out and then manually control the fan. Once we are done manually controlling the fan, then reconnecting the ECM, so it will take over. Is this possible or am I reaching here? | ||
| Rr_eater |
No, it is possible. Working it right now!! LYK Bruce | ||

I saw a post with a switch on the bar's but now I can't find it. | ||
| Rr_eater |
Yeah, you could just switch a ground to the fan, but then you are back feeding a ground to the ECM when it is not called for. Also the fan would run full speed all the time, most likely not a big deal when it is hot though..... | ||

Doing that ground out will throw a trouble code and cause the check engine light to come on. |
