I put on the "stage one" kit. I used the screamin eagle race tuner. (SERT)
opened up the air box, k&n type if air filter, and the screamin eagle slip ons.
I have since changed the pipes and put on a thunder header.
I ride the bike every day....almost.
Also I put on Metzlers. Much better handling tire. I have done some suspension changes.
The only mods I have done are functional. No chrome or looks type of stuff.
I just had it striped. My first non functionl mod, but minimal at best. Too many black Harleys.
