To be honest, I planned on having both bikes dyno tuned... but paying upwards of $500 for that does put a damper on that, especially with the season just starting. I do plan on traveling to Miller, and possibly to OK/TX where the elevation is 1000' or so, which probably would lean the bikes out quite a bit.. I'm not looking for either bike to be any faster, I'm the weak link in the equation. I just want the piece of mind that the bikes aren't running lean and I can get some longevity out of the machines... etc.
