i check,,,
wiring wiring wiring.... look for melting points, or rubbing points, especially after initial install, you will see problem areas quickly..
oil in turbo tank...
the usual stuff after that, look at belt and such , check clutch springs, exhaust springs.
the best and most overlooked thing i think is keeping it clean, i wash my sled at least every other ride, if not after every ride.....
i mean wash it too, inside and out..
not sure on the pro rmk about reeds and plugs,,
but on my m8t i need to change reeds about every 800-900 miles, change plugs about every 200-250 miles.
other than that ride it like crazy......
you will start paying more attention to the sled inside and out once you have one, especially if yo do the install yourself... which i would totally do if i was you, i did, i learned more by doing that than any thing else.
good luck.
