If I remember right it has to be at least 100
I would just limp it along till it gets too cold to ride, then pull the engine off and rebuild it over the winter, the kits on ebay with the jug, gaskets, piston, pins, etc etc etc are 230 bucks which is nottttt bad for a kit with the jug included. That will also allow you to check the frame for cracks or damages, paint it, replace or paint other parts and make any other repairs to have a LIKE NEW quad next spring. I am going to start a project in the next month or so and I will keep you all posted on that :-)
If you need any help rebuilding it im sure we have members that live nearby that would be glad to turn a wrench or drink your beer while giving you advice lol
