    Important question!

    I am for the most part new to the Water World. I raced competitive amateur motocross for 6-7 years. June of 09 i purchased a pre owned "95" Kawa 550sx. Rode it every day for three months and blew the top end. fficeffice" />>>
    >>
    Immediately following I decided to upgrade and purchased a pre-owned 07 stock SX-R 800.>>
    > >
    I am so addicted to the sport and my ski that I might take it over board, but I have a few questions that I would like to get answered.>>
    > >
    I ride my SX-R almost everyday on an average of two hours a day or every other day. When I ride I ride the ski hard. I mean really hard, I have the throttle open for a good amount of time and It feels like I am raping the machine. I jump occasionally and have gone to the surf a few times. The original owner visited the surf often (based on a visual of the carb). I rest in between ride sessions but am back on it. When it comes to any motorsports I am all over it at an advanced level. I am not trying to brag, but deliver the information to receive good feedback.>>
    > >
    I have between 185-190 PSI in each cylinder and it concerns me that it is high. I am using 93 octane and a 40:1 oil ratio. >>
    > >
    Are these skis made to be stressed to almost max? Do I need to let it rest at times? What can I do to prevent catastrophes? >>

    Re: Important question!

    two strokes are meant to be run wide open. They don't need to rest. Just be sure to let off the gas when you get a little air...
    Might as well JUMP!

    Re: Important question!

    Welcome!

    192 PSI in each is definately alot of compression for 93 octane gas!
    You problably detonating... especially if there are mods done on yours.
    I run@ 185 PSI @ 5600 ft in my SXR and I run 50/50 of 111 and 93.

    Did the previous owner specify what kind of fuel he was running?
    Good Fuel is KEY when running alot of compression.

    No I purchased ski from dealership and no information on prior usage. Interesting! High octane is expensive.
