    kawasaki pistons flat top need little help

    hi how ya all doing just a few questions for you guys in the know

    i have a gp1300r with gp1200r engine fuel injection ...
    i blew a top o ring in went the water & lifted a cylinder
    now im having my cylinder liner removed & fitted to a standard cylinder
    & rebored out to suit...

    it has a stroke +3 crank welded... flat top kawasaki pistons 80.5mm
    3 degree timing key,,, fuel controler,,, bottom of cylinders have been decked....
    heads had been skimmed about 1/4 inch

    now im going to have the cylinders done to what size should i have it bored out to ....??? 82mm 83mm think 84mm is max but need room incase need one more rebore.....

    also im looking for a set of heads that would suit the cylinders
    & who could supply them as my head was the cause of the damage
    r&d heads with o ring someone had welded the water ways at each side
    which caused the o ring to fail .....

    you have probably heard about my engine my mate posted it when i stripped it Gerry (quadzilla)


    cheers for your help kevin...

    I would get in touch with Lowell he would be able to steer you in the right direction, definitely non standard stuff you have here.
