    06 GP1300R Compression 130psi ?

    picked up a 06 today for a friend who wanted me to do the run in process for him

    running at sea level
    cold
    front 130psi
    center 131psi
    rear 126psi

    after a few heat cycles and water test they started to come up a little more

    he has about 3 hours on it now and started to open ski at WOT
    after a few runs against me and other mate he ain't to far behind anyone else find there compression over the 125psi mark ?

    his speed 66-67mph

    John Jet, my 05 had 135 per hole stock. Put Riva heads on and went to 150.

    AMY's 05 is 125 all the way across. Sounds right.

    My friends 05 had 125 and went to 140 with heads.

    They all seem to be different. The good thing is you can make it anything you want.

    John, sorry I missed this.

    Yes my swirl requires 4 thin washers. I will measure washers if you need me to.
