anybody seen this pipe in a sxr ?

[dawson]

thanks mate
i tried running water into both fittings into the silencer no diference still really loud.
i will pi$$ the silencer off and run the waterbox
just though it may have gone a little better with the water box with a bit more back pressure

IM running that pipe in my wamiltons hull. I had to shorten the sliencer about 2 inches because the engine is set back. Also had to trim part of the cable holder bracket for clearance, but it fits well. It really saved a lot of weight not having the water box and all the extra plumbing going up in the nose of the ski. Saved about 25lbs.

they fit with a smaller tank. My buddy had that and he threw in a raider chamber and really noticed a power gain, still had to run the 2.2 gallon tank.

 

[dawson]

i could not handle the noise :aargh4: of the crappy silencer any longer

what i did was to cut the exit off and cap it and convert the chamber to a center bleed system

i was then able to run the sxr water box

the ski hits heaps harder now and does not have that terrible noise any more.

all with the stock sized tank.

Those pipes make your bones rattle.

I ran that pipe in my sxipro for about a year it was loud but not to bad but i used a radiator house in between the stinger and the chamber it cut down the noise significantly. Its not a big low end pipe mid to top end it screams it just keeps on going from mid to top. Who ever said its a factory secret is right. They wont talk about the pipe what so ever no recommendations on jetting they will not tell you anything about it other then its for super stock racing after about 5 phone calls and weeks of pestering i got Group K to give me a little info on it and they seemed Guess exactly right on the jet size and popoff weight. with 93 octane ada domes and jetnetics flywheel run 65.5 bottom the lightest popoff spring silver color i think and 175.5 on high jets 3/4 to 1 turn out on high and low jets and the carbs are pristine.

Factory Pipe is always like that on not saying anything. They swear up and down they never made a 650 Kaw manifold. Well maybe they didn't but the 800 SXR Wet Pipe and the 750 XiR manifolds are in fact a 650 manifold. I gave up on them.

When you ordered a 650 pipe from Factory Pipe or Westcoast. They did not supply a manifold. Westcoast offered an aftermarket manifold. It was the same size as the OEM manifold so no real performance gain.

When I was building my X2 (in 91) Team Butch told me I was wasting my time and money ordering an AM manifold.

FPP supplies manifolds for the 750's and SXR's because the OEM manifold is a totally different design. They dont have a choice.

 

[dbrutherford]

Yeah BK I know this about 650 manifolds but my point is them denying they that they ever made one. There is some benefit over early model 650 manifolds vs late model, 1991+ manifolds. The diverter is steeper inthe late models. Plus aftermarket 650 manifolds have more cooling options.

 

[Big Kahuna]

If I am not mistaken, back then, they did not make the manifolds. They did not even make the manifolds for the 550 full pipe. You had to get a westcoast, Jetsport, PJS, or Mariner.

 

[dbrutherford]

You are mistaken because I have one that is from the 750 XiR pipe and it is the exact same manifold they sell with the 800 SXR wet pipe.

The 750 SX/SXi wet pipe had a similar manifold but the top three hole bolt pattern is rotated compared to normal 650 pattern.

I found a new 650 manifold that is finned and has the Factory pipe logo etched into it. It looks like a Mariner, they apparently made parts for each other in the early nineties. I have ads for 750sx Mariner pipes that are polished FPP pipes.

 

[dbrutherford]

Yeah I have seen that manifold as well. I had a 650 FPP I sold once that came in a Mariner box and had Mariner instructions.

 

[dawson]

this is the mod i did the the pipe
converted to center bleed
it gave it alot more power
some good bottom end
and got ride of the scream
