whats up!? just got my first standup!

[johnnyd]

I just got my first standup over the weekend and I can't wait to ride that sucker!!! Its a 94 SJ with A LOT of mods to engine done to it. guy i bought it from told me it was way too powerful for someone who hasnt ridden a standup before and at that point i had to have it!! haha we'll anyway just wanted to say whats up and cool site you got here.

[Matt_E]

Congrats, and welcome here!

I really don't think a 701 is "too powerful" for a beginner. In fact, I find the extra power to helpful (pulls you through turns when you might otherwise fall)

[Whtbread]

Congrats and good luck. If you ever head to south jersey bring the ski along. We have some good places to go jumping.

[Frosty]

Hell yeah!! Congrats bro. I agree with Matt... power is a beautiful thing.

[Mark44]

Welcome, Post a pic of that baby.

Congrats on the ski man. Bring it to lanier:biggrin:

As far as the power topic goes.....I wouldnt give a like a big bore kit to a newbie. I rode Harrison's ski when I first started standing up...like 2weeks into it maybe. It's still a 701 I believe and it about killed me. I was trying to ride but the power kept me in control wether then controlling the power.

[johnnyd]

thanks guys! yeah man, so far i have never bot anything with an engine and complained that it was tooo powerful! take some power back!! haha. im sure it will be great!

[PancakePete]

That is awesome. Congrats. welcome to the boards. :Banane01:

[yamaslut]

:arms:

[Idok]

94-95...best out of the box square ever made!!!!!!!!

[Ross_C]

Conrats on the ski...you will learn a lot from these people here.

Check out Riotradio.com in the message board section for lots of great pics...skis and otherwise.

[johnnyd]

Thanks for the welcomes. I have learned a lot of stuff by just reading everyones posts over the last month or two. still gotta stand up on it though once the spring hits!.. anyway here are some pictures. like i said, it has a lot of work done to it which is nice but wish i would have been able to do it myself.. just couldnt afford to build one with all these parts from stock. i did a compression check and both cylinders have 195psi. dont know what size domes are in the head though. maybe 32s. any ideas on what size or model those carbs are? they are some type of mikuni.

[BlowStuffUp]

ski looks pretty clean. nice find.

[orange flattop freestyler]

Nice looking ski there buddy, welcome aboard the crazy train.

You'll find plenty of friendly advise here from people that know.

Carbs look like buckshots to me, i see youre running TL too, Should be a nice snappy ski for loads of tricks

Enjoy

[Whtbread]

That's the one that was on ebay. I think the guy was from brick, nj. It looks sweet!

[Whtbread]

Do you mind me asking what you paid for it? Well I guess I already asked.

[MADMAT]

DUDE! You're the one that got that puppy!!!! That thing is killer!:hail:

[Frosty]

Yeah, I saw that one on ebay too... very nice ski.

[jetskier79]

i did a compression check and both cylinders have 195psi.

Phew, say bye bye pump gas.

[skysurfer2010]

crap! you suck! haha, i would have bought that ski if i had seen his lowered price buy it now!! you got a great deal man! very nice ski!

[johnnyd]

yeah picked it up from brick last friday, paid 1500 for it.. couldnt resist. i figured even if i got there and it wound up needing a little work it was worth it just for all the aftermarket stuff that was on it.. but when i got there is was very clean started up immediatly and had equally high compression in both cylinders so now i cant wait to throw it in the water and see how it goes. i noticed its got the 62t cases too. but i cant tell if its 61x sleeves. might wind up taking it apart just to see what i got. lol

[orange flattop freestyler]

If it aint broke mate, dont fix it.


Leave it well alone if its setup right and runs good

[Matt_E]

Be very careful with that engine....195 psi is borderline race gas.

Please use only the highest octane pump gas you can get, don't let the gas sit too long.

And no wide-open-throttle runs for more than a few seconds.

[johnnyd]

yeah it has a few gallons of 105 octane in it now from previous owner. im gonna stick to the race gas. would you guys still use 50:1 oil ratio?
also, it has ngk b8es plugs in it. should i stick with those plugs or get a differnt heat rating with the high compression?

[Matt_E]

Stick with those plugs.
IMHO, 105 octane gas is a waste of money, but it sure as hell is playing it safe.

Either do 50:1 with a high quality synthetic oil (Like Amsoil) or 40:1 with a lower quality oil.

I suggest you do a 1:1 mix of 91 octane pump gas and that race gas.

Can you run a high compression engine like this at wot for longer periods of time if you run race gas?

[Matt_E]

Yes.

If you stay away from WOT, you can safely run lower-octane gas in higher compression engines.
Example: I run 190psi in a ported 727, with a 35 degree initial advance on my ignition.
I use 92 octane gas without a problem. But, no WOT runs.

Reason being, WOT runs place the most stress on the engine, necessitating high quality fuel.

[IceRocket1286]

dang nice ski! i saw that on ebay as well.

have fun with it! and welcome! :headbang:

[kawirider00]

105 oct is $7.05 dealer cost here in NY, id lower the compression and save the bank acct

[Matt_E]

You could run 100LL (Avgas) for 4 bucks a gallon.

[skysurfer2010]

i'd run 40:1 and put in different domes. higher octane fuels are gonna drain your wallet. i'd rather use the $$ for more mods.

Yup, those are definately Buckshots, I have a carb that look just like that on my 94 blaster. I sent the stock 44 off to them and they machined the velocity stack and venturi along with the other internal circuit mods. They should work pretty good with the setup you have there.

[Fuse]

Very sweet looking ski! I bet that thing rips! Welcome to the boards, squares are a blast.:woot:

[johnnyd]

the race gas and high compression concerned me a little bit but i think im gonna see how it runs and if it is dialed pretty well i will just leave it alone.
but i definitly might change my mind if you guys give me some good reasons other than cost of gas to lower the compression. im all ears.

On my carbs... the body of the carbs are definitly mikuni, you guys are saying that the mikunis where sent to buckshot and tweeked? i cant find much on the web about buckshot carbs.

about how much HP do you guys think this set up is making?

[Matt_E]

Tough to say without seeing if the cylinder is ported.

90-100HP, maybe?
