there are horror stories out there for all platforms
The 900 is a GREAT sled, people who talk bad about them likely never owned one
Things for you to check out
oiler cable, the factory setup uses a small oiler cable that goes from the side of the throttle body to the oil pump. Bad design, they break and jam up causing all kinds of problems, They are also a real PITA to install. So the fix is a FBF cable, basically a throttle cable that splits into two upstream and drives the throttle bodies and the oil pump at the same time. Way easier to install and less problematic.
Intake boots dry rot and crack from the under hood heat, when they crack they leak and must be replaced.
Front spindles in 05-06 suck the geometry is all wrong. Change to 08+ spindles for a much better ride
VENT galore, get some air flowing through that hood and console
Better boards, the factory runners collect slush like no other, some board inserts work wonders
DIET
the 900 is really easy to lose some weight from, they are HEAVY from the factory. Trust me get stuck 6-12 times in a day and see how you feel after digging it out all day, or lose some pounds! makes it way less likely to trench/stuck and way easier to move around /lift when it does
plastic chaincase cover, known to melt. Cover with heat tape, make a heat guard, last thing you want is a bunch of melted plastic and a leaky chaincase on the trail!
front radiator delete, I am sure its already been done on your sled, but most people choose to ditch the front mount cooler or at least run it in series instead of parallel like the stock setup
flywheel separation, the flywheel can come apart inside and cut the wires for your stator, causing a dead sled. Good idea to look into the flywheel issue now before you are 12 miles from your truck

Enjoy! and get us some pictures!
we love 900's here, we know the horror stories are just that....stories
truth is its 146hp two stroke stock torque monster sled, with an IQ chassis (dragon) that can be made into a real monster for CHEAP!!
