I have a 2013 XP 902 seater turns out the guy really liked mud don’t know if the valves are broke or watt don’t want to pull the motor out at home we fix valves would like to redo the entire engine come to find out that cost a lot of money was thinking about taking my 2000 arctic cat 1000 mL two-stroke motor andFabricating it into there I have a buddy that skilled at fabricating and the snowmobile is running with all the parts that I would need what do you all think

If you’re talking about the 1000 thundercat triple then a few things come to mind. Triple pipes would be a SOB to make fit, powerband of a 2-stroke is different and you won’t have the 4-stroke low end torque, power bands are peaky and that’s a high RPM motor. I’m all for making a motor fit but there’s no way I would retrofit a 2-stroke.

Have you disassembled your motor to see what’s wrong with it?

Ironically enough I just picked up a 2013 rzr xp 900 with a blown motor and picked up a thundercat 2 stroke triple from a buddy's shop and in it went couldn't quite fit in front with out life ending mods so we set it above runs and is fast as hell you will need to add a cooling tank the motor is higher than the rad oil injection is a pain but you have to have it for the water pump bearing I am fighting belt issues now but it runs and drives have to do major exhaust reconfiguration also ton of power though its borderline the power is extreme but I have doubts that it will be manageable enough for any kind of trail stuff but would be a blast in the dunes I think
