    Fzr,fzs,sho buck

    My girl friend and i were recently bucked off our 09 fzr the machine is stock other than an air intake and exhaust, the machine is destroyed after striking a dock, and we both had to go to the hospital for neck injuries, I have been doing some research on here and found i am not the only one. Could everyone that has been bucked off there sho series watercraft please post your story and some contact info as this is going to be presented to yamaha in hopes that they will remedy this problem. I know most of you guys have changed out your intake grates now, but there are people who don't know about this problem and could be seriously injured or killed. I am not making any promises that anything will happen but it will at least get them to acknowledge there is a problem

    I would like to know about this bucking issue as well since I'm potentially at risk till I get a new intake grate. What causes this and what canwe do to prevent it?

    Yamaha is well aware.
    Good luck with your effort though.

    The only time I have personally seen a 'buck" on a SHO is too much ride plate angle. And, that was not a stotk ride plate either.

    Just do a search for buck or stuff and go through the threads. I remember reading about this all the way back to when the FZR/S forst came out. You should get a lot of info that way.

    I am really sorry to hear that happened to you.

    "I was pegged out on a lake and all of the sudden, it's as if I hit a stump!!! Next thing I know, I am airborne and then bouncing off the water. This was really fun doing 68-70 whatever my new stock ZR runs. I've read about stuffing and getting bucked but with a stock ski? Gonna be a while before can ride again. Make sure you change the grate!!! You dont want to be recovering from a surgically repaired torn bicep like I am thanks to getting tossed. Just figure it in to the cost of the ski because it is a must."

    "I was riding my FZ on light wind ripple on my local river, and towards the top end it started getting squirrely. Almost felt like it was about to do what is called a "tank slap" with the handlebars, but on a motorcycle. I quickly, but gradually, let off the throttle, I didnt chop it. I have read this thead and that advice came in handy. Thank you... that was one of those moments where I had to sit there on the ski, idling for a few minutes, until the "hand shakes" went away"

    jefros (Riva grate)
    "I have a FZS with a Riva Stage 1 (Riva grate). I was wide open (~72 mph gps) on flat water and then I backed off the throttle to make a gentle turn (still going straight). The next then I know, the ski jumps several feet to the left and apparently slowed down enough for me to fly over the bike "superman" style. I end up doing a couple of forward somersaults and then my legs dive into the water and separate causing a very forceful Chinese split! I felt my groin and lower abdominal muscles tear. Had to be dragged out of the water and took an ambulance to the ER. Luckily nothing broken but lots of torn muscles/ligaments. Anyways, now I know what bucking is. I am a fairly experienced rider and there was absolutely nothing I could have done to prevent what happened. I am not sure I want to ever get back on the ski. I thought an aftermarket grate fixes the problem. Has anyone heard of this happening with the Riva grate versus the R&D?"

    "Man, sorry to hear that bro. Hope you get well soon. I had the same thing happen to me. I didn't get bucked off cause I held on to dear life, but in doing that I also ripped & tore some stuff in my albow. I remember running at full speed and suddenly the ski turned violently to the left and I felt my elbow pop when I tried so hard to stay on. After that, my whole arm swelled up and later turned black and blue. I guess it would have been worse had I took a dive. I was running the Riva grate at the time. I am now running the R&D grate with no issues."

    I was also bucked off going 55-60 mph with my stock FZR when it just went hard right on me and I flew off head first. It was like a rollercoaster being on a rale. Went to the hospital with major swelling and bruising on my right arm. My tricep muscle has never been the same. Reported it to Yamaha and they inspected it but found nothing. BUll. Bought a grate and I have been fine ever since."

    "I got thrown a LOONG ways. Luckily, it threw me all the way over and I didn't hit anything on the way off and didn't get hurt on the landing, but it was a long swim back to it in the 59 degree water that day. That was at around 10 hours on the ski. Changed to R&D grate and pump seal kit...40 hours no buck."

    "I was very interested to see this post because I had my butt tossed while going about 70 on my 2009 FZS on smooth water this summer. I had figured I just hit a wave unexpectedly, but this bucking/overstuffing issue could be what caused it. Luckily, other than a bruised ego and a long swim back to my ski, I didn't get hurt, but it certainly changed my riding style for the remainder of the season. My jet ski was stock configuration when this happened."

    "YOU WILL NEED an aftermarket grate because of the lift the plate will give the ski, And the stock grate already is known for bucking people of at stock form so don't try the plate till you have an aftermarket grate."

    So just to confirm:

    Does this happen to the FX hulls or only the FZ hulls?

    Just FZ as far as I know. The only reason it did it on mine was I had Jims R&D plate with no shims. Opened the window on the intake grate in the 70's and pop went the weasel.

    Having said that, I am sure there is some situation where it could be forced to occur on a FX other than this specific situation.

    +1. I don't even run the R & D plate anymore. And if I would, I would use 2 shims.
