Thanks everyone for the input - I really appreciate it!! I got the sled home last night after dark, and cleaned it up this morning. It is extremely clean - I'm really surprised. I think it was maintained very well. Also, I tried a different compression tester and got 110psi mag and 100psi pto. Something must have been wrong with my tester. I hope to make a few phone calls on Monday to see if I can find out more info on who did the motor. As of right now it is pretty much ready to ride with the exception of one of the front shocks being a little soft. Thanks again for the help!
