Here is a link to some videos of my lil Fundy Performance built 730 on the bottle. It seems to do very well against everything I race. Even the big 840 motors. It takes more than just big CCs to run good. No matter the size of the motor it's all about getting air in and out of them as efficently as possible. Clutching also makes a huge difference on our bikes. Enjoy http://s301.photobucket.com/al...n46/fastfatboysvideos/

Gas Milage is damn near the same. It Does burn abit more but when I ride with my brother whos is stock. after my tank is gone he's got 1 bar left showing.. its so worth it. The power is insane man. The Torque feels like its doubled without the CDI... the cdi just amps it up even more. I can spin the tires with no effort. just brappin the throttle i burn out. Make sure its gettin enough air and its got some exhaust to get it out faster. I custom snorkeled mine with 2.5 inch inlet i believe.
