Ok so i bought my dads 03 xb9 after he picked up his new street glide. Just learned how to ride this spring and i love it. Being new to buell, and bikes in general, im wondering what you guys think some cost effective/worthwhile mods are? Im pretty sure its stock besides k&n filter and d&d exhaust. Running dunlop sportmax q2's. I'll put up a pic soon, not working on my phone lol. Thanks for any input.
