I just put in a new clutch, and she rides soooo good now that it shifts so nice. Now my lower back hurts after 20 miles. I broke my L5/S1 vertebrae 25 years ago. I just need to lean back a bit to relieve the lumbar pressure. Im looking at the Protac bolt on back rest. Wondering if anyone has any photos of this bike(or close) with the back rest installed. Any other cheap ideas for a bolt on, maybe from another bike? Thanks for any input!
