Moved up from the Kitty Cat, but the stock ZR-120 was to slow. So after some tuning & tweaking we got some speed out of it. Pulled the govenor, changed the chain to 35 pitch @ 3.60:1, different clutch and a bunch small tweaks - it goes pretty good. It will go even better when I stuff a 200cc in it next year ....
Thanks to the guys at www.recmotors.com for the help.
Changed the gearing, no governor and a few other minor things - nothing major. Info is in the video credits.
