GTX performance suggestions
Ok guys n gals...I now have all my skis running very nicely...the 99 GTX RFI is running about 60-62...what are some cheap mods that I can put on to help the mph climb some-all suggestions appreciated.
Same for my 99 Kawasaki 900STX...both of these are bone stock-a BIG THANKS in advance!!!

I honestly don't know if there are a whole lot of mods out there for those. I have found a little extra speed though using a Wetwolf AAT, you might want to give that a try, along with small things like filling in the rideplate hoples and such.

not much modding you can do with the gtx-rfi. speedo may read 60, but actual gps is around 52 (sorry but it's true). sit back and enjoy the fuel economy. AAT may work, but you already have a great pump/impellor combo in the stock set-up. you could try a pump wedge, may gain you 1 mph.
edit: AAT = adjust a thrust, not a trim system, but an adjustable pump cone to improve holeshot and top end. results on some skiis are better than others. it definately doesn't hurt performance.

We GPS'd this one at 62 on 3 different runs...but it only hits 63 then right back to 62..it begins to pull away from my 900STX in the 53-55 range. The holeshot on it is very stout already, was looking for some more on top. The engine was rebuilt by my brother-in law and me (I was there to learn and help with the lifting and the "small hands in tight places") at about 165hrs, now has 182.
Thanks for the info on the AAT...is that costly? Possible to pick up on ebay?

gtx-rfi has the 800 fuel injected engine, the gtx-ltd has the 951 carbed engine in it. they have the same hull.
