    Question '03 GP1300R pv motor - max bore?

    My #2 cylinder is toast. The scratshes are too deep to hone out, so I am going to have all three cylinders bored.

    The only modification to my '03 GP1300R p/v is a D plate in the exaust (buying a new crank - not sure if good price used or Hot Rods). I'm not looking to build speed rocket, or go crazy.

    Since I'm going to bore the cylinders, I want to get the most for my money without sacrificing the durability of the motor.

    My questions:

    Any recomendations on bore size?

    On where to have them done? (I live in San Diego, CA)

    And what I should expect as far as the average cost?

    Ouch. Get out the check book? I need my SuperJet to be sold before I go crazy. And crazy is on a limited budget.

    So your planning on sticking with the cylinders you currently have right now, just boring them to where they are useable, correct?

    I just want to get my jet ski running. So if boring them is what I need to do, then I want the perfomance gain without sacrificing the integrity of the motor as a whole. I do not want to have to rebuild the motor again.

    Or option #2: If anyone has a middle cylinder with a power valve for sale cheaper than the cost of boring, then that is what I will do.

    If option #2 is the route I go, then I would need a new piston with rings to go with it.

    Know anyone? Send them my way.

    Thanks,

    Joe

    +1 that is the budget way out if you bore those to a 1390 they have to be reniksil coated and will require motor and pump upgrades. Ron

    Thanks for the advise. If that is budget, then that is the route that I intend to go.

    Do you have a website for millinium technologies, or should I just google?

    Thanks
