I just got an Infrared Thermometer for Fathers Day and thought I would put it to good use comparing my Electra Glide's engine temp readings both while using and not using the Lenale cooling fan. I have a regular daily route I take through a town with multiple stoplights and plan on getting a baseline average temperature first without using the fan and then getting an average temperature reading when using the fan. This will be on a stretch of city road with 15 traffic lights. When the fan is on it will be on for that entire stretch of road. I've had the Lenale fan installed for some time now and haven't had any obvious signs of overheating, but I don't know if the fan actually keeps the bike cooler, or not. I am in the habit of switching the fan on at longer stops, but don't know how much it helps in cooling that hot V-twin. To get consistent readings I'm thinking to aim the laser dot either at the base of the push rods or up near the top of the cylinder heads. If there is a better place to get temp readings while actually on the bike please let me know. My little instruction book with the thermometer suggest putting a bit of duct tale on highly reflective surfaces to get a better reading, but I think doing that would melt the tape and make a mess. I'll try it without doing that at first. Since I've got the temp gun I can take temps at other places on the bike and at different conditions if anyone has any suggestions for information that they would want to know. I'll post here with some info about the affect of the Lenale fan on engine temp later in the week after I gather some data. Smitty, you mentioned doing something like this, too. I did a search and didn't find anything so if I missed some past testing here please let me know.
