    big bore gpr help

    Hi guys, I am looking for a good piston to use in my 86 mm bore gpr cylinders. R&D has discontinued them, and I need something other than a bored out kx piston. Any advice is greatly appreciated.

    I'd imagine those listed are going to be the wrong pin height.

    This is one of the things that bother me about our sport. If you end up with something like a piston (something that is consumable within the lifetime of the ski) and you need replacements, than it better be something for a whole LOT of skis.

    Also, if there is only ONE vendor, what happens when they stop selling them?

    I should have been more clear. I am looking for a piston that is readily available from wiseco. Maybee from a sled or something. I have the motor in a drag bike and go through pistons often. How many of the 87 mm do you have?

    not sure is Scotsman has any to sell - that looks like a pic of one that he is using, but give it a try. Other than that - weisco should have them on the shelf ready to sell i would think.
