    I can get Weisco to produce some 61mm 10 1/4 comp. The 652 kits will have piston, rings and wrist pin for $129 ea. Minimum order is 12, I'll buy 4.

    How do they turn the 653CC "650" into a 652 ??

    What am I not getting here??

    For just under $200 you can get "750" pistons and cylinder block, and related gaskets.

    What makes you think he's talking about a 650?

    Works out about right for a big bore on a 600

    That is right kickaha, for the 550/600cc motors. No boring of cases for bigger sleeves involved.

    Back in the day Wiseco did make a big bore kit for the XJ550/600.

    I met a guy that had a hot rod Seca 550 back in the mid eighties. He told me that his bike had a 60mm Wiseco kit in it.

    I might have one of those kits on my hot rod Seca motor that I broke a ring on. I need to send pics to Wiseco and see. Heck, I could send them a piston and they can copy it!

    BTW, these pistons are 60mm not 61 as I stated in this thread.

    I'd be game on a kit or two.
