    Porting question

    I am considering having my engine ported. When reassembling the engine after a porting, do you have to re-ring the pistons. Engine only has 50 hours on it.

    Thanks.

    are you going to have your crankcase and jugs ported or just the jugs? Im thinking of having my jugs ported this winter also.

    Cool

    take pix of piston,rings today are tough but you need to check end gap and have skirt clearance checked

    old storie,when in doubt throw it out

    doing just top end or have case's open?

    later cd

    ditto

    porting has nothing to do with rings

    if things are out of tolerance then you replace them

    Why not freshen it up if you have it tore down? Check the ring stop pins in your pistons and make sure they are not moving in. GPRinsanediego can fill you in on that. It just seems like a whole new fresh topend with the porting makes sense.

    The reason I ask is I dont wanna go through all the extra time and money if it wasnt necessary. I obviously wanna do it right the first time.
    So when I tear it down I better break out the calipers and gauges and check everything to see whats worn.

    I just cant imagine to much wear on an engine with 50hrs. But I could be wrong.

    Thanks for the input guy's.

    HAPPY TURKEY DAY!!!!!!

    You do have an 05 and Joe did tell me they did some updating to the OEM pistons. Maybe just rings. To me it seems like a lot of hassle to tear it all down and not at least re-ring. Your already into it for $200 in gaskets.
