I guess its to be expected but gosh its been a tough introduction to snowmobiles. 3800 miles has been running great all season had it on the lake heard a loud high pitched scream from the engine, shut it down. Compression tests yield 120 MAG and 25 PTO. It still runs no knocking but very little power. Could not get a good look at the piston but I assume its cracked or has a hole in it. The plug was grey indicating pre-ignition or lean condition. Since its efi, not sure what could have triggered this. Plug chops from yesterday and every time before look perfect and if anything the 700 efi motor runs rich from the factory.
So what do I have for rebuild/replacement options? Can I drop in a ZR 700 engine and use the Fuel injection/stator/ignition/pipes from my wildcat engine? What other engines will bolt up to the bellypan of a 93-95 wildcat efi? Im just brainstorming here and trying to reach the best resolution. I know I could likely re-do the top end but thats more of a summer thing when I have some down time. I'd like to get it up and running for some events later this winter. ARRRGG!!
