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'd like to compile a list of some solutions, from adding a throttle tamer to a flywheel weight or a Vortex ECU. If you want to include information about any changes to the exhaust or intake, go ahead. Some have been happy with the stock configuration, too. Please post what works for you, and be as detailed as possible. In particular, settings for any fuel or engine management devices, and include the software version where applicable (such as with a Vortex). I'll update the opening post with information as its provided.
Anything that has some impact on the low rpm performance belongs here, and if you'd like to give your opinion on what does and doesn't work for you, please include that as well. I'll also add information I've found in other threads, such as the CRF450L Mega Thread.
