    99 GP800 porpousing

    So, I heard a 1200 ride plate on the GP800 would reduce porpousing. Is this true?

    Hey dude, first & foremost you have a sweet GP there buddy. You gotta post pics of your GP. There are many late 90's GP hull fans on this site. Anyway, I don't think they are any diferrent. I owned a 97 GP760 & a 99 GP800. One of my friends owned a 99 GP1200 & they were all identical. I didn't see a diferrence. I think you may have to send it to Jim for some nice machining! He can do miracles with those plates. Good luck.
