does good work but i dont believe its very aggressive

put your 550sx long block on the shelf to save n lets swap a 650 into your ski

dont invest a ton into your 550sx...


at the end of the day no matter how much time n money you put into that ski, itll still just be a kawaski 550 at the end of the day


save you pennies n upgrade once you master that 550 as it is
 
I planned at the least to put a half pipe and a 15.5 impeller, I want a bit more bottom end and from my understanding that's what I'll get with those mods.

That ski was a blast to ride. I had so much fun on it that I regret selling it to this day. I have a superjet, but the 550 was still fun every time I rode it. It doesn't hurt to put a little but of money into your 550, but I wouldn't get too crazy. A superjet would be your best upgrade but it isn't cheap.
A lightened flywheel might go good on your 550, that was the next step for my ski, but I sold it.
