    info about group k

    Hi, new to this forum and was wondering if anyone out there has had any work done through "group k". I have a 96 sea doo gsx and was going to have a sleeper kit done to it. If you have, I would like to know if it performed as well as they claim.

    I ran the sleeper kit on my 96XP back in the day. Ran better than they said it would. Great bang for the buck.

    Man I have not heard "Group K" in along time. What I like about Group K is all the data and info that you get. Just by reading their web cite you gain a wealth of info.

    Harry Klemm's business. Haven't personally done anything with them, but the word I hear is that they're pretty straight. Had a friend once who put a basic performance kit on his 96 XP, & he was happy with it.

    I have had him do some work for me on the 800 and 951 seadoos I had. Very impressed with their work and great guy to talk to. They don't get more trustworthy than GroupK.

    Coming from a Yamaha perspective, I can't say enough good things about Group K. My 97GP1200 has 206 hours on the Group K pump gas Sleeper kit. I still have good compression and I have not had a single problem with it along the way. The speed increases they advertise are true and the reliability is unmatched IMO if you want a fast rec. ski.
