Twenty-two riders in the mixed class motos added to the fun.

Big performance boost. Cut and removed the governor shaft plugging the case hole with a glued in bolt. Also removed the weights from the governor flywheel to avoid any potential problems - it’s not needed. Be sure to keep the gear though, it’s part of the lubrication system in the engine.</p>http://blog.nashmoto.com/post/15779636949http://blog.nashmoto.com/post/15779636949Fri, 13 Jan 2012 09:01:00 -0800motorized bikennash<img src="http://24.media.tumblr.com/tumblr_lw3zjgJdg31qzyyk1o1_500.png"/><br/><br/><h2>Quick video flyby</h2> <p>Racing version of the development bike.

More photos to come.</p> <p><strong>UPDATE</strong>: I’ve given up on this idea - it’s not working the way I imagined (probably because it’s strictly air cooled).
