I have a 2008 1100 midnight custom with about 5k miles on it. I'm planning on doing some engine upgrades. I have already done the AIS delete. I've been thinking about doing cams have been looking at the PCS Triple X2. Get a Maxair engineering predator pro kit and a dyna ignition. Do I need to upgrade my clutch if I do these modifications and will all of this effect fuel mileage much?
