FX SVHO Speed guide 2022 Onwards

[Wild Thing]

Basically as title says, from what i can see the 2022 skis are not responding that well to the stage tunes falling way short in expectations. Can we collaborate together and get these FXs at their targeted stage speeds

What data do you have comparing the 2022 FX SVHO with 2021 and prior year FX?

The major changes involved the intake grate and ride plate, plus the hull material change from NanoXcel to SMC.

Does this match with your understanding?

The SVHO engine tunes for FX are only incrementally changed since 2018 (first year for the plastic intake manifold), is my understanding.

I've ridden a 19 fx Ltd, and just got my 22 fx Ltd. The hull difference is very noticeable. Smoother on the new one with chop. Heavier overall. Rideplate and attitude is better on 22. The 22 will need sponsons, rideplaye, tune, and
air intake upgrades to surpass 75. The weight is going to take some hp to overcome. But the ride quality is worth it.

My understanding is the smc is only 40lbs heavier, looking like the gym over the winter to shed some lbs

Right guys so with 5 hours runtime on the ski bone stock european spec 2022 fx cruiser svho it will consistently run 70mph at sea level 2/3 tank of fuel and 16 degrees centigrade, which I think is a good starting point. Plans will be to install riva power filter kit, engine breather and solas 13/18 with a stage 1 plus 8500 tune and see where we go from there. Stay tuned! ��.

Feel free to post your FX mods and results

How are you measuring the speed?

Gps speedo on the 2022. I know where you are going with that as the 19-21 just topped out at 70 max

I put the Riva sponsons on 22 SVHO FX. Now this thing actually turns and handles like a ski should. I have them all the way down and it is a little twitchy. I like it, but the wife might not. Middle might be better.

Speed wise, I am getting 67 even with 3/4 tank and I'm a big dude. 800 ft elevation. Temp 75, water 70. Riva breather mod, ribbon delete, sponsons, and SOON the Riva ride plate (it just came in on Monday after I spent the weekend riding). 67 seems to be the limiter for USA tunes. All using dash speedometer.

Will be getting a maptuner X for christmas and intake grate as well. Hoping to get to mid 70's. That's all I want really.

My 22 FX with breather, ribbon delete, and stage 1 on gets 72. I don’t have the riva ride plate, but I don’t think it would get me to mid 70s.

[DavidH]

I got the Riva rideplat installed, will be testing next weekend. No tune so I'm still limited by the GPS to 67. Will let you know how handling is though.

Any updates @DavidH

[DavidH]

No, cold front came in and or ride was canceled. It'll warm again before too long. Will post when I run it.

I was wondering this same thing. I've read all of the articles about the changes for 2022, but the member results on the forums don't seem to back up the hype. From what I've read, it will take all the same mods to get 75 mph on a 2022+, so you're essentially in the same place as before with 2019-2021 FX SVHO, but with an extra 40+ pounds due to the new hull.
The fiberglass hull does seem to be an upgrade, but as far as performance goes, Yamaha seems to have missed an opportunity...

Happy New Year, and I got to do some riding today. 22 FX SVHO, Riva Sponsons (lowest setting*), ribbon delete, breather filter kit, and Riva Ride Plate.
First notes with the ride plate: you definately notice the additional inches out back. The extended surface and chines make the ski track well, but seems to be "slippier" at low speeds. More planing area = less boat in the water.
This trait carries on throughout the speed range. Overall, it seems the ski is riding higher out of the water. And tracking thight at high speeds. It handles corners like my 2001 GPR with full race setup. It will bite you if you aren't carefull. *Thinking of setting the sponsons to middle position*
I am running stock tune, stock prop, stock air intake. I of course can't comment on top speed due to the limiters. However, upgrades are coming.
I will order my MaptunerX this week from *THIS SITE* (use the code GREENHULK at checkout) along with the intake grate and cold air intake. I have the stuff kit for the grate already. Then we can see if the prop is the last remaining puzzle piece.

In addition to the above, I will say the Riva ride plate is better. It is also different. It will not ride the same as the stock plate. There is a speed range around 25-35 where the ski is sitting very high on the hull, and will rock from side to side if you are not making some corrections. This may be connected to me having the sponsons all the way down. Seems like the spray is packing into the sponsons giving some additional rear lift that is causing the motion. I'll update next ride with the sponsons in middle position.
I also noted a tendancy for the ski to be able to slide around when on the brakes more than the stock ride plate. It was possible to do a nearly 180 pivot when slowing down if I had reverse and steering input (around 10-15 mph and decelerating).
The Riva plate also made the ski respond to trim much better. The stock plate I hardly noticed any difference with trim settings, now the Riva plate I can tell when the nose is up or down and handling changes as expected in either condition. This is good--
