    Old School 1999 GP1200 on GPS

    Posted this in the old school section thought some of you other guys might like it.
    My ported motor gave out on me so I did a quick top end swap to a non ported stock bore top end.
    I ran 62 mph just after break in.I made a few changes and went looking for water with my friend and new forum member Gerry.
    Last time out I made changes under the ski and gained 1.7 mph I ran 63.7 mph.So we warmed her up for 5-10 min and started making some gps runs.
    With 1/2 tank of gas ran 64.4 mph then a 65.0 mph pass.
    After burning of another few gallons of gas knocked of a 65.5 mph pass.
    My goal was to beat the 63.7 mph pass from last time so that was accomplished and I also wanted to see what kind of lift I was getting

    My tests were a success.

    I drag it behind me on a rope so it bounces all over you get a good reading that way.

    My gps is either in my hand or in my vest,if its in my vest I make sure I let off the gas before geting back on the seat so I get a good reading.

    Most times I hold the gps and watch it as I test.
    I make sure my gps readings are good.

    That mean it's safe to assume that for sale sign is no longer on it?

    I see you watched the video and saw the FSS on it.
    I would sell it but im happy riding it.(could go either way)
    I would build another ski if I sold it.

    Its still underpowered it needs porting and bigger pistons.
    Still has stock carbs reeds and air box it has pump gas safe compresion and a single pipe.
    Im having fun with it for now on pump gas,i'm trying to squeeze a little extra speed out of the hull setup .
    I have a set of pipes to play with later.
    I have a set of ported cylinders hat need bored out for later too.


    Going out again Thursday I made a couple of changes and hope to go faster.

    Last time best run was 65.5 mph 66mph will be good enough 67 mph would be sweet......
