Fuel injection is cool, I am sure in a few years pretty much all bikes will be E.F.I. I have been reading posts here and on Huskytalk and hopefully will buy a TE in the near future, I know Palmer84one is very happy with his 450. But I am still learning. What I understand is that the bikes are very lean from the factory to pass our stupid emissions tests. By installing the power up kit - less restricted intake etc, remove the sensor out of the pipe, resistor mod, will really wake up the bike. Also, there is "Autotune" - a system where you can fine tune the injection system. Am I correct so far? Is "uncorking" the bike sufficient or is Autotune pretty much a must have? Does the Autotune self learn - plug and play, or is fine tuning on a laptop required (I am guessing a cable connection to a laptop is part of the system)? I understand that the bikes computer senses when the bike is uncorked and this voids your warranty, what about if Autotune is installed during the uncorking, still a warranty problem? What is I Beat? I haven't got that far in my learning. This stuff is probably common knowledge to you guys, like I said, I am still learning, so help a Newb out. Gracias.
