Yamaha RX50 Hits a New Top Speed! | Drilling Main Jets

I finally got my 1983 "Special" Yamaha RX-50 running perfectly! After fixing the carburetor float, and drilling the main jet out to a # 120, this thing hauls ass for a 50cc!! I got this thing up to its new top speed record of 51mph, and it impressively made it up some massively steep hills! I hope you guys enjoy the video! Stay tuned for the next one, I will be starting up the TS185 for the first time after completely rebuilding it!
