if the sled is running good. and dosnt foul a plug, or spotter at certain rpms i would just ride it.
you could check your oiler for adjustment(sometimes cables stretch,people dont set them right)
but for the most part the yamaha 2 strokes burn lots of oil, because they are usually triples or sometimes 4 cylinders. which require more oil to lube all the moving parts(more moving parts more oil needed)
sure you could adjust your oiler, but if the sled is running good, everything should be good
(remeber yamahas tend to be a strong motor, keep it well lubed and it will stay that way) unlike some of the other brands which dont seem to use any oil and blow up every 1000 to 2000 miles.(like the older artic cat triples that needed an updated oiler because it couldnt lube the engine properly)
and ps. buddy who said that it needs rings is a retard and must think you have a 4 stroke.
buddy who said different oils make a difference is right.
my mtn max use to burn a shit loud of oil(thought it was normal) until i stoped using synthetic and went to the crappy tire cheap stuff(still burns more then most sleds but way less then that expensive synthetic crap)
now im buying cheaper oil and its lasting longer(hopefully it dosnt blow up)
also on my sled, if im shredding the deep stuff for long periods, my throttle on the handle bars gets sticky(packed with snow), i ususally just slap it a couple times to free it up but sometimes my oil cable actually freezes and i have to pick the ice out to get it loose again(this would make my oiler stay on )
just a thought could also be an old cable which is binding in the casing.
