I have a 2011 grizzly 700 that my dad just recently bought me and had for 8 months and the piston blew out the front of the engine. The shop had it for 9 months and we finely got it back though it was not fixed. It was overheating and squirting antifreeze out the overflow so we took back and 3 months later we got it back and said it was a radiator cap. So we took it home rode it for not even 5 minutes and it was still sqjirting out the overflow but it was not overheating so I took it back and they couldn't figure it out either and then later said that it needs rebuilt again. Can anyone help me with this problem. The only thing I can think of is the headgasket
You have a bad head gasket obviously. I wonder if they put a new gasket in? Did they use new head bolts?
They messed it up for sure. I would order a new head gasket and new studs. Pretty easy job to do with out screwing up. I have seen this happen a few times now with shops sending out rebuilds with bad gaskets cause they reused the old studs which can only be torqued once.
I think they did use the old head gasket and were doing all the maintense for now on since it ain't got a warranty now and I'm gonna try and retourqe them to see if they didn't tourqu them correctly but I'll probably end up getting s new head gasket any way. Thanks guys for the advise
Wow that's a lot of clams!!. Hopefully you can recoup some of that money if not all.

So how many miles or hours do you have on these machines before a rebuild.
Not sure what happened to his machine.
It is incredibly hard to destroy a grizzly motor. The only ways I have seen have been to run the airfilter dry so dirt gets passed, try to compress water (even difficult to as starter clutch will slip), run it out of oil for some odd reason even though they do not burn oil.
I have never seen a piston go through the cylinder. Usually it will be a crank through the crank case.
Most never ever have to worry about rebuilding a stock motor. I have one going from 2006 and it endures high rpm and wot riding for lots of its life. think it is at 7000 miles.
