    95 wave venture 700 conpression

    just bought a 1995 wave venture 700. cranks up and seems to run fine on the trailer. gauge shows it has only 20 hrs, it was sitting in a barn and seems to look like new. i checked the compression and both cylinders show 90. is this normal psi and should i check anything before putting it in the water and running it.

    If it starts and runs your guage is off. That thing would be VERY hard to get started at 90psi. They have around 150psi. Since they are both even that's good. Check/replace oil line from tank to pump, and pump to carbs. Age can make them hard. Then the vibration snaps them off and kills the engine. Couple pumps of grease in the midshaft housing. There should be a grease fitting right near the rear right of the head, it has a hose that runs down to that housing. Other than that, the Yamaha 700 is just about bullet proof.
