(see following post for black seat update) It has the brake brace in the frame for another cantilever. But, the fender mount hole also goes through that brace and is currently occupied by the screw holding the fender on.White seat is ok if that's what you want...
Black seat looks more like a Muscle Bike.
That frame is crying out for dual rear brakes too. I've seen it done before and it looks the best on one of those Spaceliners.
I have an idea for you. You could use some old shift cable and using crimp collars, put a loop in each end, make the cable long enough to go from the seat bolt to one of the holes at the bottom of the sissy bar. Also make one loop large enough to equal the travel of your springs. The reason for the one long loop, it will allow the spring to compress without have to worry if there is room in the tube for the cable to compress. Put the seat bolt through one loop, run it through the bar and attach the bottom loop to a screw/bolt through one of your bottom holes and you now have a limiter.The downfall is you can't pick the bike up by the seat rail behind the seat, because the suspension pulls apart. I haven't brainstormed any ideas to fix that, let me know if you have one!
You mean, like this one?
This was my second experience with the Dupli-Color, and a good one again. I have used your warmed can method, especially during these Fall build-offs when temps are lower during the day. Works well.Dupli-Color is the best rattle can out there in my opinion. Do you warm your cans before spraying? I warm mine in the sink under hot water. Heat, shake, heat, shake and go paint. It flows so much better hot.
I'm going to try that split cable with one lever on my brakes, but I'm a ways off till I get to that.
