Ever wonder how the Engine Braking Reduction System on your Yamaha 4-stroke works?   Do you know the exact increase in wattage that Yamaha has made to the electrical system on their Nytro sleds and the increase to the now warmer hand-grips?  Have you actually set the correct sag or ride-height on your Yamaha's rear suspension correctly?  Did you know that Yamaha changed where their track-tightening adjustment bolts are on the Vector and Apex rear suspensions?  

These are all topics that the tech gurus at Yamaha covered as well as new fuel and oil specifications and hands on lab-work when we visited their snowmobile headquarters in Pleasant Prairie, Wisconsin last week.  Both Editor Mark Savage and Senior Editor Mark Boncher took the 2-day course again this year along with just a handful of other industry and media types.  Check out some of the photos from the week.     

In addition to lab work, us media reps were given a test to determine if we had been paying attention in our tech school.  Below are a few questions from the test... Do you know the answers?  Try your hand and don't look at the answers on the bottom until you are done.
