OK, so it sounds like I should do the DJ drive mod for the bit over $400 as it's worth it, but not try to hunt for different exhausts, etc. I am also planning on doing the Mean City Cycles seat upgrade, and probably a windshield (anyone got a quick release one for sale?), to make touring more pleasant. I think at this point the longest trip I'll take is 200-250 miles, so nothing crazy. Just want to be more comfortable than I was the other day.
