Just had my main ride stolen so I might be finally starting on my AF conversion. Anyone ever figure out a solution to the frame breakage? I have an idea that I think would do the job but would add more fabrication, welding, and weight to the project.
Hijacking sandblaster's excellent diagram, I came up with this not to scale idea. Basically a 1/4" 6061 plate, or upper and lower 1/8" plates, that would follow the cradle tubing on to the head stay but even further up to be a gusset and also extends to the rear past the end of the rails to the cast piece that connects the lower rear frame together. Would obviously have a hole(s) for access to the drain plug. Could maybe even have more holes to reduce the weight some without sacrificing strength. Critiques or suggestions?
