The compression is 185/185. Blue built it and put a new crank and pistons in it about a year ago. I originally bought the ski from him, he is a friend of mine. Motor definitely rips. Everyone who rode my ski was very impressed. If you live near me you can definitely check it out. It's drop in ready to go except for a pipe. MSD as well. JetManiac charges alot for these motors without everything included. Check it out.
