Do a search for the exhaust mod over at pwctoday.com, makes a noticeable difference, that and a better carb.

That was my first ski. I absolutely loved ia nd wish I would have never sold it. I installed a Mikuni SBN-44 and a coffmans pipe and it was so much fun.

Just about anything over the stock 34 is a good upgrade on the carb. This was my first ski also. You can mod the OEM exhaust or get a Coffman. I'm pretty sure factory just did a new run of there pipes for the also.
