Well said.
I have seen tooooo many people buy sleds over the years and dump tons of money into them to make them faster, more powerful, more than the engineers designed them to be. In the end all they did was end up with an expensive, tempermental, unreliable machines that go to the parts pile sooner than later.
I always tell them to just buy a bigger motor that is designed to be reliable as an intake, carb, motor and exhaust package.
Like Mac said, get a GSX.
The only reliable mod machine I ever saw was the 89 that a coworker at the sea-doo shop had. He spent A LOT of time into dialing it in. For a stock 580 yellow motor with a mod intake, carb, pipe and water box it was untouchable by any stock Doo until the first 797 xp came out. It only needed motor work because the piston to cylinder wall clearance went out if spec from being run so much.
