Looks like there is a significant upgrade available for the 912iS. It is now called the 912iS Sport. A new airbox and software upgrade (plus a few other minor goodies) result in a higher torque curve. It looks like the parts are free for a limited time for those of us that already have the iS engine. Yay for Rotax! I'm pumped! http://www.avweb.com/avwebflash/news/Rotax-Upgrade-Promises-Fuel-Sa...
