definitely under 300 lbs and the motor is a 62t cylinder with blowsion 850 sleeves, Honda cr500 pistons, ADA super-bore head 180psi, modified 38s with reed spacer and bored and ported B-pipe, I could easily pull more hp by upping the compression and maybe adding a lightened flywheel plus if I really wanted to I could bore it to a 900, I just love this setup because its virtually bullet proof and its perfect for my style of riding.


I think you will have a very hard time flatwater flipping that. Do you have a stock pump still?
I think someone who's got the technique down could do it, but it's very tough to learn the proper technique on an underpowered and overweight ski - unfortunately.

If you really want to pursue this with your current hull (and I would not recommend it, because that chit gets expensive fast for a one-trick-pony), get total loss (skip the useless light charging flywheel), bigger carbs, 200 psi compression minimum, a big mag pump, and possibly a Powerfactor pipe. What you have right now is a lightly modified/stockish setup with a bigger bore than stock. It's a lot better than stock, but it's no flatwater setup.

Also, trim. It ain't happening without that.

Again, I am not trying to encourage you to actually do this. The cost to get you there is prohibitive and it will get you exactly one trick. Find bigger boat wakes, double-ups, or ride surf.

Sorry, had the page loaded for awhile before I responded. For sure a setup wake would get you further. Took me about 6 months of practice before I started getting mine completely around. I don't want to say it's impossible, but be prepared for the grind.

And you have a hull purpose-built for backflips.

congrats buddy on the attempts.. ski sounds great looks great.. backflip that $%^& so these haters( real Talkers) shut it.. the best flips are on hulls that " cant" do it.. :headbang:

haters? you must mean the guys that have done it and know its next to impossible with the equipment that he is currently working with, right? if not, then you are one of the dreamers that believe in superman, batman and spiderman and have never flipped anything but burgers at some greasy spoon.

Exactly what I was thinking. The "haters" are the ones who actually have done it, on a few different setups. ":):):):) the haters" is nothing but dream speak from someone that hasn't.

And I didn't say it was impossible - just very difficult and taking lots and lots of practice, a trim system and mag pump, and possibly more power. And for what? Flipping ain't that great. But it is fun.

i have seen many setups above and beyond this setup, have one hell of a time getting around. thats why i'm very skeptical that it will EVER happen. you cant just pray for a flip to happen. there are many pieces to make the flip puzzle happen. this puzzle is missing some key pieces.................. i'm a realist , not a dreamer and i'm not going to sugar coat it.

I haven't done it and will call myself out all day long. I think your ski with CATS trim would be a perfect surf ski ( our surf sucks 'round here). I have my 718, 144 mag, bpiped, and a light(Er) weight bob. I'm here to tell you the weight in the hull makes the biggest difference. I ran this package in a RN last year and could get it upside down. People try to make flat water skis out of oem hulls all the time... It's just not the quickest point of attack. Listen to the big boys like Matt_E and buzzkill, they've been around the block. The hull is 90% of the time a must in the flat water world. I still think its an outstanding ski, and in no way am I doubting you... But you need more than what you got without a big boat wake.

id put a great wager on the fact " HiS hull wold flip, not a spin flip but definatly able flat water a set up wake.

but let me guess, a beefed up 4 cylinder cant beat a v8 either right??? blah blah blahhhhhh

go kill someone elses hopes

^^I'd say hull geometry might be as important, but probably more important than weight. You see the glass XFS being flatwater flipped with a stock 701 (including stock exhaust) - though by none other than Rok himself. There is video of a stock or stockish 701 BOB being flipped - I think by Jack Sutton. Neither of those hulls are particularly light, but their geometry favors flipping. And even with that, they need expert riders to pull it off, mostly as a marketing gimmick.

I am no flipping expert - I didn't get them around in my carbon Superfreak until I put a 1000cc motor in it. But I did have over a year of practice with a lesser engine (760) on it, and I feel that once I started getting them with the bigger engine, I learned quickly what worked and what didn't in terms of technique. With that, I am confident that I could now pull them off on the same hull with the 760 setup I had before. It's a lot easier to learn on setup that doesn't work against you and lets you succeed easier.
I learned far more about successful flips in less time with a larger engine than I did in one entire season with a smaller one. It's tough to learn on a relatively under-powered setup.

If you are determined, look at lots of videos of proper flip technique and buy a trim system and mag pump, at a bare minimum. There are a few videos of stock SJ hulls flatwater flipped. There may be hope for you - but it's at the end of a very very long road. Myself and others have been there, on more capable setups. Good luck.

What's your qualification to comment on this? Having hope? Maybe get a job with the Obama administration? :moon:

certainly not needing a 1000 cc carbon superfreak to do a flip

Nobody claimed that you do. In fact, you seem to mostly argue fictitious statements no one has actually made.

So let's hear it, which setup are you flatwater flipping?

definitely see where your coming from and I agree, its just that I don't have that sort of power at my disposal, but I have tons of time to practice it and backys really are not even my main focus, I havnt even attempted a barrel roll yet! and even if it cant complete a flip its still 100x better and more fun than my heavy waterlogged stock hull

Hey, have fun with what you have. Sounds like an awesome rec riding setup with some power behind it and quick handling. My comments weren't really meant to discourage you from trying, but rather to discourage you from focusing too much on a single trick that takes most riders quite a bit of money.

I think if you want to get a "substitute" for bigger power or a different hull, try to organize a v-wake session with two capable boats (either loaded down wakeboard boats or big cruisers). A proper v-wake will launch you like you wouldn't believe and you will get it very quickly. My first successful flips were on a very heavy -2 Roundnose with a 760. No trim.

I understand, this whole vid was just a last second "hey, we're heading back to the house, lets try some backys" lol im sure if I spent a day messing with wakes and techniques I could get pretty far, and what fun is riding when you have nothing new to try or accomplish? its a work in progress and will eventually get somewhere, might take a boat wake or a v-wake but ill get there! just take determination.
