    Hello from the UK!

    Hi guys & gals, new to the forum & jet ski scene but not new to forums.

    Ive just picked up a GP1800RSHO needing some motor work.

    Its got some upgrades -
    RIVA intercooler kit with HKS blow off valve
    RIVA 16psi supercharger wheel
    Upgraded supercharger clutch
    RIVA intake system
    R&D R2 reflash
    R&D billet steering stem
    Renthal fatbars
    Ribbon deleted
    Innovate AFR gauge
    Boost gauge
    Carbon fibre hood
    RIVA sponsons
    Dedicated I/C line

    Ive currently got the motor out on the bench, the issue was water mixing in the oil, so heads off ready for skimming & refreshing, i just need to get the coupler & supercharger clutch off then i can get the block skimmed too.

    Ive ordered ARP head stud kit & a full gasket set.

    Also waiting on a new seat cover from Jetrim & decals from IPD!

    Interesting choice for a first ski....has head been pressure tested? common for them to crack and require replacement so I wouldn’t spend anything until you know the head is good.
