Rickter xfs questions

[mister_skat57]

Hello

I have rickter xfs 2012 (the person I bought from, told me its first generation)

the hull is heavy compared to the most recent one. I am able to flip with it on a wave of boats. On flat water its more difficult since I have a small engine: 701 61x power factor pipe 144 setback pump i dont know what is my pitch impeller


I don't really want to have big engines.

I have around 30 hours of use in 2 years, it would not be profitable to put a big block


what advice would you can give me?

changed hull for a smaller one in the style : max bun


or upgrade my engine to 760?


thanks

Are you running the powerfactor pipe wet or dry? If you are looking for bottom end response id convert the pfp to a wetpipe or consider a b-pipe for that motor setup regardless of what hull you end up choosing. Just my .02

I ran this setup in my chan for a while. I liked how carefree it was. Could easily flip it and didn't mind to fountain until it was barely floating. My cylinder was ported and I ran an ada head. Kept my pipe dry. A gp800 nozzle helped it get to the higher rpm sweet spot for pfp dry. If your prop is cutback then you could try spacing it back out 5mm or so to bump up rpm too. Those older xfs are heavy though. I rode one with a dasa1000 once and couldn't get it around cleanly.

RRP pipe or try the pfp wet. Msd TL or zeel.

Imo you need more power to make flatwater enjoyable. The more you ride, the more you want more power. Ideally stepup to a ss900, 964, 8 mill 950 etc.
760 cylinder swap would be a waste of money for flatwater.

Try a larger nozzle and bend the impeller until max thrust is obtained.

I would put a lot of weight on Hornedogg79 actually having experience with this and listen to him.

I'd also get a zeeltronic and if you can deal with race gas bump your compression way up.

at the end of the day its a small motor ski. even great riders will struggle to consistently flat water flip a 701. either accept that its a boat chaser or step up to a bigger motor

this is 100% false

Get a zeeltronic set up, bore your nozzle and put domes in to run 110. 30 hrs isn't much time so the extra cost of 110 won't be that noticable. Unfortunately with a smaller motor it takes a lot of time and practice but it is definitely doable and is still a lot of fun

and i 100% disagree with you. im gonna say 75% + of guys that are capable of fliping their heavy 701 powered ski in surf or off boats have never rode that 701 powered ski out of a flatwater flip. yes 701s can flatwater flip but the AVERAGE rider is not CONSISTENTLY riding out of them. Even being able to flatwater flip a small motor, a larger motor is way more fun both boat chasing and flatwater.

Yes, I remember you. You gave me advice when I wanted to do my jetting for my power factor pipe on my 701 61x.

The nozzle of the trim is already bored at 90mm. I’m not sure I understand when you talk about cutback on the prop. Does it have to be cutback? If I buy an ada head, what dome do I need? Between a ported cylinder and a stock, is the difference huge?

i agree with you, It would be better.to go with a bigger engine but i am from montreal and the summer is short maybe 4 month its a lot money for the time i use the jet
and for now my setup is ok for me lol

I'm referring to how close the impeller is to the stator vanes. If a prop is "cutback", aka machined on the backside, it can screw further into the driveshaft and sit closer to the stator. It improves efficiency of the pump but makes the prop feel taller. With stock bore 33cc domes should be around 190psi and safe with 93 octane. 31cc is race gas territory. If porting is done correctly it's one of the biggest upgrades you can do to your ski.

Find out what prop you have first, there's a lot to be had from pump tuning especially running your pipe dry. Your trim ring/steering nozzle or reduction nozzle is 90mm? 85ish is max on a stock nozzle so either you have an aftermarket nozzle or the wrong measurement.
Porting is an absolute night and day difference. Cutback is just another piece of the puzzle for pump tuning. You can absolutely squeeze enough out of a 701 to flip off of your own wake. I prefer running my pipe wet so I can hit the wake slow(due to more low end power) works awesome when trying to learn off of your own wake IMO. Not as much height though. Much easier to tune than a dry pipe on a 701 too. I think wets just more fun to mess around with but that's just me.
Definitely do the programmable ignition and make sure you've got high compression domes. If you choose to continue running pfp dry, adding some timing and race gas will net good results.

I used to flatwater flip a ported 61x cylinder on unported 61x cases, with a stock single 44, 144 mag and a laydown pipe. It took a couple hundred fails to get decent at it but once you dial it in its brainless but does take some effort. You just gotta tug on the bars a bit harder than you would with a bigger motor and have everything about your setup wake perfect.
With big power, you can make mistakes and still get it around. It's more fun when you can get your head higher than a couple feet off the water.. But 701 flips can still be fun. Makes it so when you do step up to big power that it becomes absolutely effortless.

I agree. Have known Jon for years. He has always found ways to ride with much less than most and can pull out tricks with a small motor that guys with bigger motors cannot do. One of the most naturally talented riders I know.

Thanks BK, that means a lot to me. I'm certainly not an expert but figuring this stuff out is what keeps me interested. My current gig doesn't pay very well so making the best of what I have is life rn.
Roseand may be on to something with the nozzle bore. I think the Thrust nozzle can go bigger so that may be what he has. I'm not sure how much bigger is better for a 144.. My 65v nozzle is only 85mm. The difference is the shape and volume. I believe Pro-tec used to make one that had a similar bell shape but straight, no up angle. There's a thread on it buried in here somewhere.
Figure out what impeller you have. In my skat setback 144, I prefer a skat c75 13/18 over a hooker 9/15 no question.

I think i Take the wrong piece, i take the picture of my nozzle. Tell me what you think about my nozzle

and my impeller i think it's old model i show picture of that

i read your explanation about the cut back ... if i understand its better if a take it when i buy my new impeller c75 13/18 ?

 

[hornedogg79]

Ok your nozzle is fine. That prop is an older design. I think you will be happy with a c75 13/18.
