95 400 Xplorer help needed

[zlrider]

Had this posted in ATV for a week without a respone.

Last weekend was riding the 400cc liquid cooled 4x4 and it started to run rough and blow a lot of extra white smoke out the pipe. Mileage is 2400 and oil injection is working properly. Pulled over and noticed the coolant resevior was empty. Radiator coolant was also a bit low too but not too bad.

Is this a head gasket? How bad? How ugly to repair if I'm somewhat mechanically inclined..or how expensive if I bring it to a dealer.

Thanks.

mark, it does sound like you have a blown head gasket or a cracked head. expense i don't know but a single cylinder four stroke should not be to hard to fix with a good service manual. sorry for the bad news.

i have seen this a few times .it could be a head gasket but chances are the piston skirts broke off and cracked the the case .pull the exhaust off and take a look .if the skirts are broke it is easy to pull the head and jug off after you remove the plastic and the gas tank .then look down in the crank case and see if is cracked in there .hope it is not .but if it is you will have to find a new engine .hope this helps .good luck .
