Since i bought my bike new i've never taken it to a Yami dealer. I've done everything my self from changing fluids (oil + transfer case), exhaust, coil relocations, new coils, BAK kit, AIS block off plates, PCIII, rear fender elimination kit. etc. There's more i've done but you get the picture. You usually can find info on any mod your interested in etc. on this site. Just spend some time and do a little research. The search feature on this site is worth it's weight in gold. The more you know, the more money you'll save to put towards more mods. Good luck.
