    Standup Handling Questions

    On the fourth try I finally got up on my standup (750SX). Once I got up, it seemed easier than I thought it would be. Don't get me wrong, I still fell over (like I was drunk) but it seems to get easier with practice.

    My question regards handling. I have a fairly open intake grate and a stock ride plate. The ski seems to porpoise some even when I am as far forward as I can be. What's the trick to keep this from happening? Ride plate and/or intake grate change (if so, which ones)?

    Incidentally, I'm 6'-3" and 260#.

    Thanks for the help.

    Craig

    cut off your lower legs and lose 80#

    the js and sx hulls are very bouncy, especially for those of us who are on the large side (6'2 230#)

    Practice mate, Get used to trying to stand on different positions on the tray. You can fit an aftermarket rideplate for the moment, i have a worx on my ski and it cuts out a lot of it but when i give someone a shot who has little experience on it porpoising still happens. Practice , practice and a bit more practice oh and more throttle

    Is the intake grate aftermarket??? I also have a worx intake grate lots better than the stock one..

    The 750's are prone ot this. You need to get a new ride plate. Look for a long Jet Dynamics ride plate and that will help. Hull extensions work good too. You can find those at Blowsion.com

    Thanks for all the pointers. I'm looking at a ride plate and practicing almost every night. I have notice that since I am able to stay up, my stomack muscles don't hurt as bad.

    I think my intake grate is aftermarket but I am really new to these and don't really know what the O.E.'s look like.

    On a slightly different note, there are two water discharge nozzles on the sides toward the front of the ski--how much water is supposed to come out of these? The left (port) nozzle has a little water that comes out but the right one doesn't seem to have much at all.

    Thanks again for the replies.

    If it is like mine

    One is the engine cooling bypass and should always have some water coming out, variable with speed

    One is the bilge pump output if there is one installed.

    If no bilge pump, post pics of the cooling paths and we will help out

    Also, when you are practicing, try standing differently. One leg forward, then the other, especially in turns and slides. Once you get the feel, you can do all sorts of things

    when I was 6'1 145# the 550 was a lot more fun, 650 was too powerful. now at 230# the 750 might have enough, but my 550 doesn't
