    Squish????

    Whats the lowest squish you can have on a grp1200 setup? With a riva head or a r&d head? I know what the spec is on seadoos, just not on yamahas. Any help would greatly be appreciated.

    .050-.055ths is more than enough. Most people try to set up around there...for racing or rec ski's...

    Provides good crisp throttle response and better overall performance.

    I also ran a 50:1 oil/fuel ratio.....some might trip on that but I have ran every 2 stroke I have owned on that ratio using Redline or torco ...both synthectics.

    Never had a piston fale because of oil breakdown.

    Hope that helps...

    Just my Opinion...

    yes, I've heard of others running that redline at that ratio. I hear its superslick stuff.
    Thanks for the squish numbers, I'll have to check mine out.
