MY MISTAKE! I thought it was yours from the pics on the facebook page.
Just wanted to give you an update that I am NOT the builder of the CS5 you featured. Just the finder. Don’t want to take the credit of Wild Turkey Fab.
Reader Daniel Thornberry (link to FB page with build pics) pointed me to a
his really trick little Yamaha for sale on E-bay (linked while it lasts). And no, I do NOT know the bike or the owner. Trick little build though. That pipe is the bomb!
