I have had 135 psi each cyl since I have had this motor. Two different head in it to try and lower compression. First a riva with 38cc then an Ada with custom 36 dome that gives 200 psi usually. I still only have 135.
Motor is a circuit racing surf ported cyl. That was said to pull like a sob. I put in a new top end bc I noticed a crack in one piston skirt when I inspected. Less than ten hour on the motor.it is a 701 bored to a 760. Using the 760 domes.
Why can't I get the 200 psi it should get. This ski has no hit..please help!
