Ok dads/gurus, I need to verify a few things for my build. We are building national 50 semi stock bike. I've always been told that you can't weld on the frame (gussets). But from what I read it doesn't say that in the rules. It says you can't remove material. Can some shine some light on this?? Also, can we run aftermarket axle? And does the wiring harness have to be in place or can I remove it? Probably silly questions for you national vets, but before I drive 20hrs I wanna make sure this thing will pass tech. Thanks
