I knew it was only a matter of time before I was gonna want more out of my ski than my RIVA S II. There are several things and parts ive been looking into like the RIVA rear intake kit, but Ive read that there is water ingestion with this setup. I tend to ride 90% of the time in the ocean. For the most part, I ride around normally, no tricks , spins , but I do like to jump waves. Again these are not huge waves. How sesitive is this actually. Ive read all the prior threads on the rear intakes and everyone seems to have something different to say.
