Agreed you cannot have both a surf ski and a flat water ski, i tried. The 1000 dialed and set up right is too much power for surf. I currently have mine detuned so that it will last forever, but its no flat water stock SJ BF set up. But then again without major skills what is in that combo? For a REAL surf ski all you need is a 701, but great lakes arent real surf most days. Its all about knowing what you need and your style of riding. For what you are asking there is no good solution only compromise.
 
Wax...Yea we are trying something a lil diff to get to that result in blow down,Using a motor with this large a piston with a short rod stock crank and changin the time it takes the mixture to travel across the piston,ignite and get out the exh port.using a smaller lower triple exh port and larger valve to close them all.. Some r&d with much lower boost,transfer and exh timing are being done,I believe eric said he talked with you about some of the things we were trying with this specific motor.

I dont think its a compromise really,if you have a 50/50 need then yea it is.But If you ride surf 75% of the time this is what you build for. Its near impossible to build a sj hull to be capable of flat water backies and still be manageable in the surf..it would take a hella huge motor...A 950 or so like im talking about in lighter weight -3 to -5 hull would certainly be capable of both. Thats kinda the main goal really. I dont think many of us wana pay for or maintain 2 skis for diff purposes.

Its deff possible at 750dcc and that hull if you are a skilled enough flat water rider, Im hoping to make it easy to do with not much flat water skill at 950....lol

Depends on the 950, the hull, and your experience. It's not as easy as some make it out to be.

Only if you use it as a shield.

I talk to Dan L, he said Art did your engine. What package did he put together for you.

**Edit, your running a Kawi Set up huh?

Yep, just a massaged SXR engine....nothing you'd be interested in....lol

Talk to Matt about his previous setups from Art. He should have some good input on the subject.

I've ridden his 771. It was fun. I just don't' want to get toooo excited an engine. I need to build this crazy ass hull first.

The thing is, I don't want to keep having to move up. I want one engine thats going to satisfy for a couple years. Hopefully forever.

Thats why i've been looking at a 4-5mil stroke.

Funny (or sad) how it always turns into flatwater vs surf......the thread was about 89 vs 94, now look at the discussion.

I'm with Matt though, the flatwater flips are much harder than they appear. It takes a fair amount of practice to get it right, even with power. Ask me how i know lol. If your timing or setup is off, you can have all the power in the world and you still won't get around.

I'm also in agreement that a capable flatwater boat is far too much for most in the surf, and a good running 701 is a great surf setup in an a/m hull, or a mild Stroker in a Sj hull. The rest is a little overkill.

In the end it's about what YOU want and what type of riding YOU do. I'm 2 hours from the surf, so I built a flatwater boat and don't regret it one bit. I get criticized by many of the locals, some of which frequent this site, for investing in that kind of setup, because they prefer surf, or dont agree with the cost of building a flatwater setup. The reality is a five hour round trip drive for a tank or two of riding is not enjoyable for me, nor is the hour of cleanup required once I get home to keep my ski in good shape. I am within 30 minutes of several lakes/rivers, and that's where I do most of my riding. I've ridden more this season than ever before, had the most fun, and made the biggest gains in my riding ability as well. I'm happy with my choice........

The end result is that everyone needs to build the setup that they will be happiest with and enjoy the most. It's all about riding isn't it? :)
 
Depends on the 950, the hull, and your experience. It's not as easy as some make it out to be.

Mainly the depends on the 950 part..most any lighter -4 hull or shorter and any good rider should be capable.I ride surf 99% of the time,never even tried a flatwater backie before my first try and landed my first attempt with trim right on the plate and almost went around for a 2nd if id of seen it comin that fast. That was on a hull just like yours with a well built 940. Im sure I could do it with far less power with more practice,but its just never really been my thing. If Im riding flat water im usually chasing a boat in the river behind my house.. jumping and carving its wake.

There you go - you had the experience, the right hull, the right motor.

I've seen people try it on my 1000 Freak with TL, big carbs, 148 pump - and they failed.
 
phil...yea thats the title but the subject says 75% surf motor......then later gets into talking about possibly wanting to flat water flip


experience...lol um no.. ridding surf and flatwater freestyle are not even close to the same imho..second time ever on a flatwater built ski..Im not saying a newbie could do it, but anyone thats use to a standup ski should be able to.
Hull..yes it was a -4 freak but like i said most any -4 or more should be fine.

Slide flips don't really count as "doing backies". Sure with enough motor and the right setup most people could do a slide flip, but thats not really a judge of of skill or representative of flatwater riding. They are, for the most part, "power flips". The combos and setup wave flips take considerable skill and time to master.

It's like saying "I got 10ft of air as I shredded the surf today". Going (riding) off a big wave doesn't make you a wave shredder.

And, for the record, the title was 89 vs 94........nothing about flat or surf, just asking for a motor comparison. :)
If the 94 is too much, then the 89 is likely too much as well.

The opening statement is "what is the power difference between 89 and 94mm SS dasa motor" and this thread ended up with another freaking discussion over surf/flatwater set ups.

can anybody elaborate on these two set ups?? As anybody tested the Dasa SS 94mm?
 
This has all been good stuff that applies to my decision.

Yeah, I am probably 75% surf and 25% flat water. I wouldn't mind being able to flat water flip my freak, but it's not vital. I do ride some places that make a full size tank mandatory. I also want a charging system and ideally pump gas. So yes Masterblaster.....you are pretty much correct.

I was fairly happy with my old "baby scream" motor. However, I have this little itch to be able to flat water flip. My motor threw a rod through the cases so it's time to upgrade! I have had a lot of back and knee problems so I don't ride as much or as hard as I used to so I was trying to keep the cost down in a range easier to justify.
I was originally thinking of buying something used, but the used prices are so high and you never know what you are getting so I was leaning toward starting fresh with something new.

Chad

I know bro..you are no diff in thinking than a ton of us surf guys lookin for a decent allaround ski and motor...Some of these flat water guys are just super sensitive about everything fnnn thing. Like they cant read the subject...what now it has to be in the title to address it? yesssssh.
Im also pretty sure you could care less how you do a flat water flip,as long as it will do it,slide to a flip... hop 180 to a flip, circle a setup to a flip.

Phil..if thats the case why did you come up short 75% of the time on slide flips in tona and the colonial race,The few times I saw you do flips into a wake with some speed you made it around with much more ease? I know didly about freestyle so dont go gettin all bent outa shape about it..its just a very basic question. I also dont think any junkies think it was stupid to build a flatwater ski...if you got the disposable income than why not?

Maybe you guys should read the subject and entire first post......nothing about a certain stroke (though he was contemplating 3-4 mm), and nothing about flat vs surf. As Steve said, it's about 89 vs 94, which I have has personal experience.

Torr, I'm not sensitive about anything, just stating my personal experiences and opinions. I can read just fine......

As far as flips, anyone will tell you that a slide flip is the easiest by far. I couldn't flip to save my ass until late this summer, regardless of the type I tried. I've never claimed to be a great rider or a freestyle expert, but I do have experience with both setups.

It's good that Chad has found some good info from this thread.......it's about riding how you want and enjoying your setup. It doesn't have to turn into a pissing match like it always does.
