    Need some performance upgrades advice

    Hey guys, I just bought my first ski a 2001 GP1200R....the only aftermarket part on this ski that I am aware of is the Solas impeller. I have gotten it up to 63-64 mph, I would like to get it up to around 70, I have a price range of 600-700 bucks, what things can I put on my ski to get a little more top end speed? Also, two weeks ago my jetski would jump out of the hoel and on plane withing seconds. I took it out Sunday and Monday and when I give it throttle, it starts plowing through water eventually getting on plane and I can run 62-63 mph, I have no idea what this may mean. I am just looking for some answers so I can get it fixed. Any advice will help, thanks guys.

    Put one of Jim's plates on,that'll give you a few mph and you will lose top speed if you put a free flow exhaust on without any other mods.Chances are you may be too close to shore practising your holeshot and sucking up stones,thats why it's not jumping out the hole the same as it was.
