2008 Dyna Street Bob, 12K miles, SE A/C, Reinhardt Cross Back Duals w/1.75 baffles, ThunderMax FI controller. Bike has run rough when warm since it was new. Had a PCIII when delivered from dealer, I put on the ThunderMax after about 6K miles, hoping I could tune out the rough spot. :small3d023: When starting cold, the bike runs very smooth, as it warms, it develops a rough spot between 2500 and 3000 RPM (approximately, no tach, based on similar speeds on 08 ultra). The warmer the bike, the wider and rougher the rough spot. At times, I can not ride in 4th gear below 55 MPH without the shudder making my teeth chatter, forget 6th below 80. Dealer, as always, states that all Dynas are rough. They will not take the time to get it completely warmed up, or they may be right. Any one else with this problem? Any solutions? I have heard that the MOCO designed in some roughness on the Dynas, but can not confirm that. Any help appreciated, thanks in advance.
