I have just purchased a 2010 tenere with 2k on the clock. I blocked the AIS and removed the snorkel. The bike performed like it should without all that ADR crap on it. Question was will it run too lean? Could I get a definite answer. NO. I have the Australian model which as the Unifilter foam filter as standard. I did not want to do the fuel mod / O2 etc if it did not need it. I decided to find out for myself and booked the bike into Dyno Time in Perth. After extensive �runs� the verdict was the big thumbs up. The only time the bike came even close to running lean was at 1/4 throttle. The guy who ran the test said if I had a commander fitted he would have tweaked it at that point but the rest of the range was spot on. $100 for peace of mind�.Priceless. Btw it pulled 44 at the back wheel. Time to get off the keyboard and into the dirt !
