Hi people!

My name is Gerrit, 49 years old. I have owned a Yamaha XT500 in the past which i loved, now i own a 2006 XT660X for 7 years now. No mods except for Remus cans and a Magura wheel bar. I want to know more about other performance mods like filters and stuff,...and i have a feeling that i hit the right spot joining this community ;-)
