Best Carb/Pipe for 960ccm PV engine ???

[Kawastyler]

Hallo,
last weekend first ride with my new toy..........

Its Seadoo 951cylinder with 76mm crank.
Engine goes awersome.....but carb(44mikuni) and Pipe(b-pipe 42mm diameter) ar from a other ski and must back in it.


Wats the best singlecarb for this engine and best Pipe.
knows somebody of you,were i can buy a manifold like FP type 8 or EME without pipe????


Thanks for your help,Andy

Andy,
You need at least a set of dual 46mm Mikuni's for carb setup.
Get your exhaust manifold and headpipe bored out to 48-49mm.
Make sure you run a Jetworks Flow Control valve on your water feed to the stinger.
This would be the 1st things to start with for now,
Then upgrade to a Power Factor Dry Pipe later...

Hallo Supertune,
Yes ihave Flowcontrolvalve......
I have a pair off 46s,but with removed venturi.....do you think it works???

What N/S and jets you think to start???


Thanks,Andy

PS: were can i buy thes Pipe???

I thought the 951 sea-doo motors had the carbs and exhaust on the same side??? I could be wrong

I don't think he's using Seadoo cases.

 

[Yohns Kustom Fabrikation]

Kawi Cases??

 

[CARBONX2]

Kawi Cases??

Yes, 76mm stroker

 

[Kawastyler]

Kawi Cases??

Yes,Kawi......

Next spring in billet

 

[CARBONX2]

Yes,Kawi......

Next spring in billet

Didn't realise it was that much work:hail:

OMG, thats the best Frankenstein engine yet!

 

[SXR-FOREVER]

OMG, thats the best Frankenstein engine yet!

Hell yea it is!

 

[dbrutherford]

So am I correct to assume you cut two cases in half to make that?

I agree, best frankie engien I have seen! I am curious to see how well the port passages from the crank case line up with the SD cylinder.

What kind of machine work is involved in putting a Sea-Doo 951 PV cylinder on top of Kawasaki cases, if you don't mind me asking???

What you mean "Frankenstein"????

Im a poor guy.......a lot of destroied cases in my shop,but all at 2.cylinder.

 

[dbrutherford]

Yeah I am poor too I have cut a case or two in half in my days but it was always from water injestion. Keep up the good work!

To much......

Spacerplate cylinder to cases, spacerplate for yamahaexhaust,lenghted and stroked crank, carbon bedplate, welded intakemanifold, cncd coupler, starterbraket.........

I would do a minimum of dual 46's but dual 48's I think would work best for your application. I agree w/ SUPERTUNE, bore your manifold/head pipe to 48-49mm. If you can do a EME exhaust that would be nice, but a type 9 would work well also if you can get it to fit.

The name Frankenstein is a popular term for mismatched engine components such as a 61X case with a 760 cylinder on top. This looks like an inexpensive way to make a bigger displacement engine with power valves if it's not to much trouble with the machine work.

Is the base bolt pattern the same on the Sea-Doo cylinder and Kawi cases?

Did you happen to check the port timing on the engine you built?

The reason I ask is because if the Sea-Doo stock 951 engine uses 140mm length rods with a 78.2mm stroke you would think there wouldn't be any need for a spacer plate with 133mm Kawi rods and a 74mm or 76mm stroke?
