I live in Kentucky and I'm trying to find a shop to get DX retuned after a bunch of mods. I had it tuned by my dealer but they told me they had never done the mods I had done before. The tune in the bike is close but it has a hiccup at 4,000rpms that is annoying and it only does it sometimes. Also the bikes does not pop on deceleration. I had the bike tuned with a SEPST. Thanks for any advice.
