    787 Porting

    Does anyone still do 787 porting? I'm doing a rebuild and would like to get a mild port job done while its out of the ski. Or I'd be happy to buy/trade for a ported case.

    If you are building a 800 for performance go with 800 RFI cases...they have a water cooler on the bottom. Good for 100-150 rpm.

    I have a nice set for sale if you are interested.

    Contact Group K. Not sure if they still do porting, but they cut a head for me on my 951 motor.

    Why port a 785? The 720 and 785 have race porting stock!

    What would Klemm do? widen the exhaust port, raise the rear boost port,
    and make the cylinders appear as though Klemm did a lot of porting work?

    He opens the intake way up. It has a butterfly shape when you look straight at it. I have a set with the port matched Buckshot intake mani.
