well, the first thing i will say about break-ins is to dont be afraid to run the hard. i personally think and believe that with all the better technology we have in materials and machining parts and the tolerances have gotten so much tighter that it is actually good to get the pressure and RPMs up right off the bat to help the skirts seal against the cylinder wall. also, there is NOTHING in your sale contract that says "break them in this way or your warranty is null and void" so i wouldnt worry about the snow pictures at all! those can not go against you in any way.
i guess i should have been more specific, the timing is not adjustable by you. it would have to be adjusted by the dealer, because they have a special computer program called Digital Wrech that they plug your machine into, and can look at all these crazy things. and just FYI, your onboard computer keeps track of the machines highest RPM and highest engine temp it has ever seen, and when plugged into digital wrench, the mechanic can look at those numbers and get a good idea how hard the engine has been ran before. but again, not much to be worried about there. but anyway, the mechanic can advance or retard you timing on the computer. it may also bo something like the TPS sensor or the crank position sensor need to just be recalibrated, that can also be done by the mechanic on the computer.
these EFI quads are a lot like cars now. a lot of the tweaking has to be done by the dealer on the special computer program, as most stuff is electrical now, not mechanical, for better or worse. i assume being so new they are still under warranty? all cost should be covered under warranty, and if not by chance, tell the dealer to submit a goodwill waranty for the mechanic's labor because they are so new. goodwill warranties are a for sure thing, but if you are out of warranty, it should be accepted on something like this
side note: digital wrench shows everything. it'll show the air intake temp, it'll show how many time a plug has fired, when the machine is running and hooked to the computer, it will show piston position, literally every little stat it shows on the screen. our mechanic showed me this one time. i was blown away by all the things you can look at in real time, and all the history the ECU stores. if you get the chance to watch a polaris tech do this, take the opportunity, its really crazy to watch
