Bump, I will buy as many sets needed for you to produce a few sets of these adapters!
After getting my "no expenses spared" NX50 build running, I have determined that my stock-crank-with-forged-conrod and 70cc piston is quite out of balance, causing the fuel to foam in my Mikuni VM20, which causes fuel starvation, which doesn't allow me to ride at higher speeds, etc.
Long story short, I could either pay to get my crank balanced somewhere (yay -_-) or donate to the cause here to put out a few sets of something that would help the community. I'm on board with the latter! :D
