Popped a piston on the Mag side of my Mach,, 3 days ago.
I was on a tight trail that came out to a 3 foot snow drift and i had no where to go around it an 6 sleds behind me.
i decided to crack it to get through it but forgot my vents were open :(
the snow dust was so thick it almost took me off the sled but what it did do was take in a large amount of snow that made it to the pistons and popped one.
Cartronics said i had water in all three carbs and i was lucky i only lost one.

its funny thought, itis snowing like crazy here and i have no sled.
it sucks :cussing:

I feel for yeah budd. My friend has a 1999 Mach Z 800 and he just blew a piston. Cost him 3500$ to fix canadian. ???

I take it you took all the snow filters off? There is only one way in for the snow and that's behind the windshield. Having the vents open makes no diff. if everything that came with the sled is there.
I have packed so much snow in the filters powder riding the sled could'nt breathe anymore and started choking itself with raw fuel and fouling plugs. :doh:

dont let machzzzzzz1 see this thread he will never accept that a mach blew up no matter how it happened and it may put him in the emergency room from a panic attack if this is confirmed!
He will need serious counceling when he finally accepts what happened. Just a thoughtfull warning for machzzzzzz1! :devil:

I can hear him now :D

3500 to fix a piston?did he also replace crank and cylinder?

Poor poor Mach Z :(

What 462 mx means si that the guy blew all three pistons took the skirts out and screwed the crank.... Mite of done some cyllender damage too. Needs the whole engine rebuilt........OUCH :(

RIP

Cartronics got it done late today. It cost me 430 canadian. only one piston needed to be replaced.

Mikadoo what does your filter look like.
The one in mine that i am referring to is the one on the top of the air box.
i hit the drift so hard that when i stopped and lifted the hood the filter was laying on top of the exhaust pipes.
But the filter looks so porous that snow would just pass by.
to discrbe the filter i would say it looked like a piece of scotch scratch pad used on auto body work.

SKI-DOOD, yes that's one filter, where is the one above the gauges?
Both are course like you described. If everything is fitting right, the air passes just above your gauges first, then thru the second filter on the box. My filter above the gauges is what kept plugging with snow and choking the motor out.
Eating enough snow will take a piston because it washes the cylinders down with water. Sounds like you hit so hard the sled flexed enough to pop the filter off and gulp a big amount of white gold.

I agree 110% with Mikadoo. On my 98 Mach I always rode with the vents open. The only ones I had closed were the very front ones to keep a bit more heat in the pipes for a bit better performance (and I broke trail many, many times in lots of powder and real cold weather). The only thing that lots of snow in the hood SHOULD do is maybe get into the clutches and cause the belt to slip (same with water crossing). Maybe also check your sled for any other signs of unnoticed damage! But like Mik said unfortunately sounds like raw snow went down the airbox!
