So I'm wondering about the projected/expected longevity of the 900ACE Turbo engine. Anyone have any idea how many miles roughly one can expect out of it? Anyone with a 1st or 2nd year model able to answer any questions about this? Anyone with some serious miles on theirs yet? I have to think it will be more than a 2 stroke engine, but I have no idea... are we talking 10K? 20K? +/-???
