oh yeah, I've already thought about all of that, the whole back end is getting cut off and rebuilt in heavy steel, front neck is getting replaced with the 73' Yamaha neck, and the belly bar & crank tube "gone", will have steel twin bars w/forward controls, down tube, heavy steel, motorcycle front and back w/ motorcycle old school drum brake.
Brother I am going ALL-IN on this build.
Sounds like a great way to learn to weld, lol! Excited to see the finished product. I just picked up a 60s dirt bike in rough shape that I'll modify with bike wheels and predator 212. After yet another frame crack on my Schwinn I'm done with stock bicycle frames
