Used Factory Pipe Limited chamber. Powder coating isn’t in the greatest shape. $275 plus shipping

Used Waveblaster Factory Pipe Mod chamber. Could use a fresh powder coat since I had some wood glue leak on it when we moved. $275 plus shipping.

Hi @aqualocos, that is definitely one of our 750 SXi dry pipes. It appears the manifold was welded incorrectly. I wish we had a manifold left to help you out with but we don't. Unfortunately we haven't made any of the pipes in about 10 years.

Glad I could help!

It sounds like you have a set of Pro-X pistons. Which your piston clearance should be around .10mm or .004" and your ring end gap should be .25mm-.40mm or .010"-.016"

I can get you all the Speedwerx mounts. Send me an e-mail with what you need and I will get you pricing.

So forced air induction wont work on a 2 stroke. Then how does this supercharged sled make 325 hp? http://www.youtube.com/watch?v=RmkneJ7HTxU Just a little information on this sled. It has a completely stock Arctic Cat 800 H.O. engine which makes 157 hp stock on 91 octane. The only...

Do you know how many cc's the domes you have are? I would highly recommend turning your stator back to the factory mark and not advancing the timing. The MSD enhancer doesn't pull enough timing out at the higher RPMs to be safe with the Speedwerx pipe.

Finally a Yamaha watercraft cylinder with auxiliary exhaust ports and Nikasil plating!

There is a EGT set- up out there that some watercraft racers use. It is the Racepak Hot Tach set-up. You wouldn't want to use a Koso or Digitron set-up because I don't think either set-up is going to be completely waterproof. I don't think either one was designed to be submerged. As far as...

Bump - lowered price to $135 shipped in the lower 48.

I have a brand new U.M.I. steering system for a Yamaha Superjet. Looking to get $135 shipped in the lower 48.

Luke, If you are just considering lightening your stock crankshaft, you could try Twister Crankshaft. I think they did a couple for Jeff.

Luke, Give Falicon Crankshafts a call. Since they are almost in XScream's backyard, I would guess they had something to do with their stroker crankshaft.

I don't have any notes on setting up a SXR with 48mm Novis. But I this is what we used for jetting on a 750 SXi Pro Factory Kawasaki Superstock. 135 Main Jets 140 Pilot Jets 2.5 Needle & Seat 115 Gram Springs

Our manifold is different than the standard Riva/Factory Pipe exhaust manifold. We used the same casting but we modified the length. We also removed the Riva logo from the ones we sold and put our logo on them. We also made some pipes for Riva Yamaha. It's the exact same pipe as ours but we...

Here is my recommendation for people that want to listen to me and don't want to take a chance ruining their sealing surfaces. Clean as much of the gasket as you can with a razor blade obviously not getting too carried away and digging into the sealing surface. Once you get all of the big pieces...

And don't use sand paper to clean a sealing surface. Your goal is to have a clean and FLAT surface. So unless you are using sand paper on a granite surface plate and you know what you're doing, don't use sand paper.

NEVER use a scotch bright attachment on a air tool on sealing surfaces. You are asking for trouble because even a Scotch Bright attachment will remove metal at high speeds. I've seen quite a few cases and cylinders that have been ruined because someone had cleaned the sealing surfaces that way...
