One of best Mods I have done, ShowTime sold me mine, he is a stand up dude, you can't go wrong getting one from him. I think Honda made a mistake with our bikes and showTime fixed it.
Gas Mileage has never been a big issue with me, 32-34 which is low, but I blame it on my wrist, it moves around a lot. but when you get out on the open road you don't feel like shifting it into 6th, around town 4th is about has high as I go. Maybe I can find a good Dyno tunner in the Louisville/Lexington area.
Keep it between the lines, enjoy the 4th of July
