I recently picked up a 86 TRX250 utility in decent shape. I just did a compression test and it was 110psi. Is that too low? What should the compression be?

welcome to the forums. down load service manual, and get it from there. not all engines run the same psi ?, but ideal for that model would be around 125 psi. they will run on 100 psi ?, but barely !..lol.
