Thankyou Professor .. I learned a lot of what to and what not to do from this site in the last year...Now if i could just figure out how to keep spokes from breaking... ( think i may have my drive sprocket to tight. ) I soldered the copper header with a high tin content solder and copper plumbing fittings to mate my expansion chamber...People have said the solder would melt. Ive ridden for 5 hours straight @ 3/4 throttle and have no problems with my welds melting...Oh, also, the lights (5) are converted to LED ( book reading nite lights ) from old generator powered light sets...I just drilled the holes and JB welded the LEDs to the bezels...1.50 each. ( from Walgreens)..and they last forever...Recently a neighbor gave me what he thought was a '50s bicycle horn. It's actually a 1915-1924 plunger operated motorcycle horn. My next step is to enclose some of the frame with spare fenders, pop rivets & gutter tin.....I love these bikes !
