Sxr factory b pipe overheating help

[jonny waters]

Hey Guys I got a 2008 Sxr that is running pretty solid except for the pipe getting way too hot !!! It is sizzling all the way though.
Mods:
Stock Sxr jetted to the correct specs for the factory wet pipe. Some compression at 185psi.
Screws are one turn on the bottom of pipe and tried out one turn on the top of pipe. Water routing is as everyone recomends.
... dual cooling ... - head of pipe to singer and out the pisser. Bottom of pipe to top of head. Other head to ou the pisser. Both pump to both intake of pipe manifold. Any feedback helps. Thank u

You can try parallel cooling.

Look if the water holes under the screws are open...take manifold of and connect a water hose to it and blok off the other connection then look in the exhaust manifold....

What's parallel cooling ?
and the waters inlets from the pump are good. Is there a way to see if the tuning screws are good ?

Btw this is a new setup. Just built this ski. The first time it touched the water since 2009 was yesterday

I gave u info to check the holes...disassemble exhaust take it outside the ski and attach a hose! Then check if its spraying water in the bend!
U don't need paralel cooling!

Ok sounds good. Will try that out today

The holes are 1 mm so getss clogged up after no use for a long time

I think may be a little confused on what ur saying. So I'm taking the whole pipe with manifold off. I hook up a hose to one of the inlets off the bottom of manifold and where am I looking for water ? Does the pipe stay completely together or am I just making sure the manifold is not clogged

 

[aqualocos]

Only the second manifold with the screws don't know how to say it in English

This thread details exactly what aqualocos is trying to explain:

The pipe is made of 3 pieces. Starting from the motor...
Manifold
Headpipe - the curved section
Chamber

The head pipe has 3 adjustment screws and 2 water fittings. The 3 screws block 3 matching holes in the inner part of the jacket. The holes are about 1/16". They can get clogged with carbon or other debris.

Remove the headpipe. Hook a water hose to one of the water fittings. Block the other water fitting with your finger. Hsve one screw open, 2 closed, and let the water flush the hole. Repeat with the remaining 2 holes.

Dual cooling is when 2 lines from your pump to your manifold. The engine and the pipe remain one circut with higher pressure and volume.

Parallel coolkng is when one line from your pump goes to the manifold and the other goes to the pipe. The engine and the pipe run as 2 seperate circuts. Then engine gets the same amount of water but the pipe gets cool water instead of water pre-heated by the engine.

You need to make sure your parts work right before you try changing your cooling. I only mentioned it because i had a SXR and a SJ. I brought them both to Bad Boys Racing. The Sj came back with dual cooling and the SXR came back with parallel cooling. I dont know why. They were both limited class skis.

O sorry understood u wrong i have parallel cooling to on my sxr think the difference is in the manifolds yami bpipe is 1 stock feed on the right exhaust port and can bore extra left side...sxr bpipe feed is stock in the middle.

Right on guys. U guys are awesome. Will try it out and let you know how everythinh works out !! I now have a little more understanding about this.

 

[jonny waters]

I've never troubleshooted a b pipe before.

 

[jonny waters]

Ok guys finally got back to the ski. Checked all the water fittings and everything was good. BUT...... here's the funny part. When I bought the pipe it came with the a hose already attached that I didn't think twice about checking. And of course I checked that cooling line that goes to the front bottom of the chamber and it was clogged with a bunch of sand !!!!! Was confused until I took it off and noticed it has a 175 carb jet in the fitting. Never seen that in the factory pipe. What do u guys think about that ?

A full waterbox is quiet but backs up the exhaust. The motor cant wind up until the water is cleared enough to let the gases flow. Jets are used to dry out the waterbox. Its the concept behind the jetworks flow valve, except the jetworks uses a spring so you can run less water at low rpm nd more at high rpm. Your jet is fine s long as it is not clogged and nothing past the singer fitting is getting too hot at high rpm.

Did you swap the fitting on your pump? The oem fitting is fine for stock setup. Add a pipe and it does not give you enough Collingwood capacity. Ask me how I know. It's a 1/4 x 3/8 barb 90 degree fitting.

Perfect sounds good buddy thank you. Just seemed weird to me that is was randomly in there

Ski is still over heating and can't figure it out !! Driving me crazy.
