I have an 2001 Arctic Cat, ZR. It originally came from Quebec and was raced in the snow cross league there. Not bad shape with all things concidered, When I ran the serial number it comes up as a 440zr snowpro but there has been some mods done before I got my hands on it. The engine's top end is Blackmagic if not the entire engine. It has plenty of power and has me wondering about the displacement. Is it a 440 or not?? Compression test last year revealed 185 and 190psi a side. Also I am having to run VP-116 which can get costly. I am not sure when i should pull the top end off to check for wear and what parts are still available for Blackmagic engine mods?? Any sugestions??
