if there is such a question, would like to know what the lowest compression on a honda foreman 2002, 4 wheel atv, that the unit would still run.

I have one bought it new, (my son did) it was stored for at least a year outside it hasnt been taken care of but it was still running and getting us to lots of tuff places .........it quit on us 2 sundays a go, has fire gets gas and the engine isnt locked up has oil in it. When I put my finger over spark plug hole it blows it off. dont have a gauge. but will have a mechanic check it.

I live in Ky and we are going to get what I can out of it where would you try and sell it, is 800-1000$ crazy to ask for a non running bike
