Well i have been looking into 440's for along time now and i finaly found one that is half way trail converted and stuff.

its a 2003 Ski Doo MXZX 440, motor as just been rebuilt, ran for 10 to 15 seconds and the ring broke. have no time to fix, the sled has awesome power and has been trail converted, have all stock parts, my loss is your gain. $2500, got a new piston coming and two extra cyl., just need to replate one of them

It doesnt NOT have oil injection how hard would that be to do?

I am looking for an estimate on how much it is going to cost to do this project (or fix the sled to be trail ridable)


he said he beleives it has the extra coolers.

Im guessin who ever put the rings in didnt have them seated right around the piston....If I were you I would keep the sled and fix it since you have the parts for it and the oil injection I would leave off. Its not that bad mixing gas and plus all ski-doo oil tanks leak anyway.
