I cannot answer the direct questions but with some engineering, welding and math skills anything is possible. I was in my mid to late teens and riding a few unsanctioned races on a 125 Kawasaki when I wrecked and broke the forks. With no engineering I was able to replace those with some Honda forks I had. Basically, cut the frames and welded them in place. Made sure the geometry of the forks was 'close enough' with mine and my dad's 'eyechrometers' we got it to work. I actually saved enough money to enter my one and only Pro-Am using that frame (different engine). I came in 4th, so pretty good for some young punk from Northern Ohio.
