cleaning any thing snow moble related is just a waist of my time why ?
so when u blow the bottom end and have to pull the motor and drive it 2 hrs u don't have to wash the oil off your hands and risk a dirty steering wheel.
I for 1 wont work on buds crap with oil and crap caked on I cant stand a heavy neglected sled.
nothing worse than some guy hauling his neglected pile of crap up on a trip. then more times than not it breaks. now u are in the woods elbow deep in grease just trying to get the pos running to get back to the room so the rest of the crew can go back out and have fun.
like stated above some one lifts hood on a dirty pos I will pull out a strap if neat and tidy I will dig in help get it rolling with out hesitation.
guys I know who own shops say they always do better work on a obviously maintained toy than the neglected dirty pos.
just way nicer working on something clean.
I have used a pressure washer selectively under the hood. spray under hood with some sort of engine degrease then usually get under y pipe joint then belly pans and a quick rinse from a distance.
