Low rpm performance is a common topic for this bike, especially the L models. I think the L has gotten a bad rap for flame-outs and low rpm surging, even though some of that appears to have been addressed by the RL, and many have reported an improvement after a 1500 mile break-in period.
I want a list of what I've done to my bike, and I'd rather it not be used to generate ad revenue, so this is the perfect place to post it. I'll keep the opening post current with how the bike sits.
