I installed the Rush slip-ons (2.25" baffles) and the PCIII with the map as supplied from Fuel Moto. I think it is still running lean and hot. I am getting pops on deceleration and shifting, a sure sign of a lean mixture. I'm going to get the bike dyno tuned within the next couple of weeks. When I made my dyno appointment, I talked to the mechanic about the heating issue we all seem to be having. This shop is not a HD dealer, but he is an authorized Power Commander tuner and his shop has a very good reputation in my area. He said that dyno tuning is a good idea regardless of your setup (I would expect him to say this since that is his job, but I trust his opinion based on his reputation). The bikes come from the factory quite lean, and there are so many factors that affect tuning, that any pre-loaded map, like the one I have from Fuel Moto, is basically just a starting point. He also highly recommended an oil cooler on the 110b engines. They just run hotter and depending on the riding conditions and air temperature, it is not uncommon to see oil temps above 240 degrees F. I have an oil cooler from a small outfit called Blenn Air (
www.blenn-air.com). I like this a lot better than the MoCo option, and it really works well. It's also easy to install and looks much better than the MoCo oil cooler. Downside is that it is many more $ than the MoCo version, but I feel it is worth it.
Bottom line is get a fuel management computer, get a dyno tune, and get an oil cooler, then relax and ride!
