    Default 8mm Super bore stroker...945cc's

    OK here is the beginnings to my 8mm super bore stroker build. I'm using 87mm flat top pistons to start which will make it 903cc's but can be bored to 89 which will bring it to 945. I will be using an ada girdled head and custom cut 951 domes.
    Removed the sleeves from the cylinder tonight but need to wait on the pistons before installing the super sleeves. Need to determine the correct sleeve placement to get the port timing I want.

    What's the life expectancy on a build like that.
    Riding an '89' is a splash from the past!

    Shouldn't be that bad as it will be set up for freeriding. No 9500 RPM WFO runs like a race motor. Really once the motor is built it'll be nothing to maintain. It uses off the shelf kawi small pin rods. They are custom pistons but readily available and not much more than regular wisecos.
    I'm probably going to have wiseco do a 88 and 89mm run of pistons. I have to wait a bit as custom orders have to be for 24pcs.
    I'm planning on offering this motor setup and a couple other variations for sale. I'll also be offering a 89mm superbore cylinder that will work with the stock crank. It'll basically be an 845cc bolt on.
