I have a Modshop 990 engine for sell. It is based off of a 2002 800 engine. Crank has been trued pined and welded by SLP. Engine runs on pump gas (91 octane) at elevation (6000 plus). I will include the carbs bored to 41.5 mm by OVS, SLP 900 pipes, all the electrical, and the primary clutch Arctic Cat,6 post clutch new two seasons ago. I'll sell everthing to you for $3,000. I havn't been able to put too many miles on the sled the last two seasons as I was finishing up college. Let me know if you have anymore question.
