GY6 150cc motor?

Hey guys I was just dicking around on bmi's website when I spotted this little number and it gave me a idea I was thinking about building a racing mower with something like this and have it linked to a 3 speed 1200 or 2300 depending on what I could find I thought itd be interesting to get some input and maybe see what you guys think on the matter. I figured itd be interesting to have the cvt run the tranny so youd have a wide range of gears just in the 3 gears sorta like the vari drive just stronger.

As always input is appreciated!

Guess it would help if I put in a link!

Remembered it may be a good idea to throw in a link!
