There is no shortage of information on how to make a jet ski faster, we all want faster skis, but there seems to be little information on how to make one more fuel efficient/quieter...without ruining performance. I mentioned in another post how Group K switched out 40mm carbs for 38's on a '97 SeaDoo GSX and got way better fuel efficiency without really hurting performance. For me it's not so much about the money as it is about always having to get gas (where my new STX sips gas). Also, the loudness of a two-stroke can be a little much when I'm trying to convince kayakers that I'm not a monster because I love jet skis, anyone have ideas on how to quiet one down, again, without killing performance.
Thanks again for all your help.
