full spectrum 49mm carbs

[WaveDemon]

to take this a little more off topic, I actually have a black jack and am trying to "upgrade" to a 48mm modified stocker. I'll hold on to the black jack a little longer incase it ends up to be better.

They are good carbs............ have a few friends that run them on their race ski's................. harder to tune..............

as far as freestyle specific, I would lean towards the Full Specs........... Ed know s what he is doing............ he sets each set up specifically for their use.........

Once again, I believe that's a misconception. According to who? Blackjacks are some of the easiest to tune, most forgiving carbs available. If you buy them straight from Jetworks, they'll be set up for your combination and you get awesome tech support from Art. Brazina is reportedly pretty hard to access at times. Full specs are great carbs. I believe part of the fascination with full spec is the fact that they are so overpriced. It's the most expensive so therefore it must be the best, right? Also, if a particular builder who is popular at the moment says they are the best, then they must be, right? I'm not knocking them at at all. Just saying that most(if not all) the opinions about Blackjack carbs come from people who have no experience with them at all and from the tired old Group K article on carbs. My question is this. If Blackjacks carburate flawlessly AND flow more air than any other carb on the market, what more can another carb do? I don't get any free stuff from Jetworks or even any discount from them. I just get really weary of the same old crap that is based on nothing.:banghead:

Hmmmmmmmmmmmmm, you know, most of us know what we know because of what we hear about.............. whether it be first hand experience or word of mouth....... My personal experience, Chris has a set of Blackjacks, has had a hell of a time getting them right............ still hard as hell to crank............ Bill Haig (Several Time National and World Champion) runs them on his SXR, has said they are hard to tune (Compaired to others) but once dialed in they work great......... Kennie McKenzie 2004 Nov. Limited Ski Champion runs them, took a while to get dialed in, but they rip now.....

you know...... If you get a set of custom carbs from any of the Manufacturers then they damn well better be just about spot on, that is why you pay the big bucks.......... But, pick a used set up and try to get them tuned.............. you cannot always call Art and find out what will work..... or is every set he makes identical.......... With the Full Spec's Ed taylors each carb for their entended use......... If your lucky and know who you bought them from he can tell you what you need to do to make them work, even as far as if you need to drill out one of the circuits or fill in a circuit depending on pipe and setup (Ask Jason about this).

He must not be too hard to get ahold of, Jeremy Parr called him in Havasu Friday or Saturday Night with some jetting problems, Ed was willing to get up from the Dinner Table and come out right them to work with Jeremy (Believe they ended up working on the carbs the next morning)... I have heard the same complaints about Art also.

Personally, My Stock Mikuni (Non OEM) carbs work perfectly for my set up.......... dont see any reason to spend that kind of money...... My engine builder actually recommends running a single carb (TLR - Current motor setup).

No you may not be sponsored by Art, I would be hard pressed to believe you dont get discounts, everybody that supports dealers/builders ends up getting some kind of help whether it be advice, help or discounts.... anytime anybody ask about carbs or porting all you can say is contact Art........... But that is ok, you are just supporting your engine builder......... we all do that......... But, by doing so, in this topic you are biased towards his carbs.............. again, nothing wrong with that......... When TLR was still big into PWC's I told everybody to see him.............. I dont even know if he is still fooling with ski's now at all............

I rode crammit442's dual 48 Blackjacks on his 6mm ADA stroker and they kicked arse. I think anyone who has ridden his boat will tell you the same.

Holy crap thats for sure. That thing hit way too hard for me. I'm just getting back into ski's, but I've ridden a ton of different boats and Charles' ski by far hits the hardest. I'm still waiting to ride one of Tricky's skis that Charles keeps on telling me about. I really can't imagine any more power.:bigeyes:

Way off topic, but so far my favorite ski that I have ridden so far is Harrison's. It's got just the right amount of power. Harrison if you get the time shoot me a pm and let me know exactly what you have done to your ski. You told me at Smith Lake, but I forgot. Thanks. :biggthumpup:

 

[waxhead]

I am sure the blackjacks work well
the issue i see is they dont have the bosster venturi in the middle that hekos boost the signal

this doesnt mean you cant tune them as well as any other carb it just means they will be more suscitible to changes in temp , elevation etc

this is because they are metering off slower moving air and not of the smaller booster venturi

 

[2XLR8]

I think the reason SOME people have problems tuning the Blackjacks is that they are using tuning practices they use on other carbs. I have found them to be easy to tune. They normally will work with higher pop pressure and this make the unexperienced tuner run into unknown problems. The most common is trying to lean the bottom end when in reality you have a rich highspeed circuit condition. I have used them for racing on Superjet Superstock at altitudes from sea level to 4550 ft of elevation with out having to pull the carbs off. I have been told the reason they hit harder is the lack of the booster venturi. You have to take in consideration the air filter top. If you block the top then the air comes from the sides and if you have a booster its in the middle not on the sides like the 12 holes on the Blackjacks If you dont have an obstuction then the carb will allow more air as the engine is reving up. If tuners tune them and get them dialed in for a particular application,then any similar aplication should respond the same. In other words the same jetting specs, and if you already know it then whats hard about that?
Crammit blieves on the product as well as I do and thats why he speaks ot for them. Kerry Hibdon runs then and has found them to pull the highest RPM of ANY carb he has tested and he has tested most. Maybe thats the reason his two stroke GPR hits 88.5 mph and maybe even more now.

 

[Big Kahuna]

I dont think I have read anywhere where anybody has said they are bad carbs...... People just spoke of being harder to tune...... or maybe just not the carb for their setup.

Wasnt this thread about someone talking about how much they like their new Full Specs???

 

[CG Racing]

I think they may be harder to tune for the novice. Once you've got one set done, the rest are a walk in the park. Never needind to mess with them after initial dial in is priceless to me(or should i say half the price)

I Really want to ride your boat Charles, it seems like it scares the crap out of everyone who gets on it. I think it scares them on different levels, one level is the pure power, the other is the money others spend to get a lesser boat.

sorry for the hijack, still interested in trying some of those full spec FREESTYLE carbs.

 

[RoyalFlush@PCB]

you gotta ride one of the team scream boats out there... HOLY SHIOT.. royal flush's (5mil team scream stroker) and jason stoyer's (??? team scream motor) boats hit HARD

ive still yet to ride a "pissed off" LPW motor besides yamaslut's .. so i dont have an LPW motor to compare the team scream's too. but ive ridden quite a few boats in my time.. and the team scream ones so far are the ones that have really stood out in my mind.

i mean, REALLY stood out!

I'll have a LPW 6mm stroker ready for Daytona...

in a WCF hull...:sneaky:

 

[superramjet]

Ive messed with a bunch of carbs and never believed in spending a bunch of cash on a nice set, until now. I spoke with brazina at length and decided to give them a try. It's the only mod i did to my ski, I tuned it at body beach sunday after the races right after I bought them. Huge difference in bottom end.

That's awesome. Being happy with the performance is what it's all about!:biggthumpup:

Brazina has forgotten more than about carberation that most carb manifacturers will ever know.

His carbs are awesome, I use them on everything I have.

[waterfreak]

Yeah, I'll secong that!!:highhorse: :clown:

I personally love my 48mm Riva powerbombs and it's all I wanted to say!
I'm sure all other carbs are great, but the best carburators anywhere are the ones that are dialed in properly.

Just my own .02

On that note, I think that adding a Lamey cylinder over a set of aftermaket carburators may give a bigger bang for your buck!

lamey cylinder with pistons, head, sleeves, pv around $3-4K, 49 full specs $1k 3-4 times the gain over a nice set of carbs, doubt it.

Full Specs are great no doubt but I have Riva Powerbombs and love them as well. I wonder if the difference was due to the carbs or Ed's reccomendations. Malone was telling me that Ed used to come over to his boat when it was acting up, take the carbs off, tinker with them for like 2 minutes, put them back on and the ski was like better than new. Ed has mad skills in the carb department and I firmly believe that you get what you pay for, he does the best job setting things up and makes sure they flow equally.

I paid $1500 for a used lamey pv motor, ported w/ powervalves and kawi flat top pistons :Banane01: Best invetment I have made, Power bombs were a deal as well :biggthumpup:

 

[2XLR8]

Carbs should not be so tricky to dial in . I believe if you have to drill or even plug up an above idle fuel hole something is too touchy and is more than likely to be on the edge of tuning. This does not make it better. Besides how much better can they be? There has to be a limit on HOW much . Is a 20.00 burger much better tasting than a 10.00 burger? You can only cook it up to a certain goodness. Beyond that its a matter of taste. I can't see how you have to factory tune or massage every carb to make it perfect. Can't you just rejet it to work on any boat. I would hate to buy a used set of carbs only to find out that you can only use it on a kawi when all I own is yamahas and sea doos. Its like having to flow bench EACH carb before it ships. I remember reading something about that. If the top is done in a CNC they should all flow the same. If they dont what are you going to do? get a grinder and make them flow the same?

 

[superramjet]

good arguement, unless you've actually tried them

I have tried Full specs 46's and Riva 48's on my boat. For some reason my ported 701 motor just liked the bigger carbs. I have only used the Riva's on the lamey motor. I tired them and wanted to sell my OEM 44's almost immediatly.
