B pipe help understanding

Location
Uk
Ok this is my first superjet I bought a year ago 2014 model and it came with the b pipe already fitted by the previous owner. and compared to my old Kawasaki 650 it’s a beast maybe too much for my riding
i just had a few concerns this year I fitted hot hands to it early this year (UK) but found the water to a lot hotter than what I’m used to that much I sometimes moved my hand away is this normal for a b pipe
and can someone explain to me what these 3 taps do on the b pipe I’ve tried to read up on them I just can not understand how they make a difference to performance and also which is top and bottom as I read some where that is confusing aswell. I didn’t know if adjusting these back to base setting as because the hot hands was hot is the engine getting too hot which is concerning me . the single pisser does come out really well like a arc so there is some flow there. one of the taps on top of the pipe is a fair way out is this correct
i do have the oem exhaust pipe with it was tempted to put it back to Standard with oem jets

i wish I could find some diagrams ect to work out what it needs to be at and maybe service manual for the ski

any help would be great

Thanks for reply i get they are used for tuning but what do they make difference to the flow of water ? As that pipe looks a big diameter how’s 3 thin needle screws going to affect itit obviously does. I guess I just want to know how it works to understand how to adjust it to suit

The water spray cools the sonic wave. If you open the top one some this will make it think the expansion chamber is longer giving one bottom end power at the cost of top end. If you just open the bottom it makes it think the chamber is shorter giving you more top end with some bottom end loss. Mid justnkinda splits the difference... you have to have some water flowing out of one of the 3 to keep from melting hoses. This is a very basic description... there are many more in depth conversations. Mayne some in those links.
 
How are your cooling lines routed? Can you post some pics of how yours it setup? That will help a lot. The screw adjustment will have no affect on the water temp coming out of the pisser or hot hands. The screws are strictly for tuning the chamber temp and where water enters the exhaust stream. Post some pics of your setup. Theres lots of info on water routing for superjet bpipe setups on here. I wouldnt run hot hands unless you have dual cooling. What are the avg water temps you ride in?
 
Persist with tuning this pipe. These pipes have a fantastic reputation for giving sizeable power gains with reliability. You’ll get used to the extra power with some tray time.

The only sane reason for going back to a stock pipe is if you are selling the ‘ski and putting the pipe on your new ride.

Depends on where he pulling water from. If from after head pipe and if he was running very little water into chamber he could be making really hotter water..

Thanks for replies I saw a diagram and the b pipe header looks has a water jacket round the outside and the screw taps look to block the flow of that sorry very new to having a b pipe
I’m going to fit a new ride plate after work so will take pcs of hoses and post tonight it still has the original head so only one water outlet

Right I’ve checked my water hoses from th back of the ski one comes from the pump splits into 2 one goes into bottom of b pipe and one goes to front of ski then spits off to 2 again one to front of exhaust other goes to pisser which has a join for hot hands

there is also one from head to top of b pipe

I also looked at the b pipe 3 screws the bottom one I felt with my fingers and was slightly out middle one was closed and the top one was out the most

you have to loosen the set nuts, then close the screws, then count the revolutions turned out from closed. (1/4 turn, 1/2, etc) Cannot do it by feeling how far it is sticking out. Dont put much pressure when closing. does not take much to close off.

Been a vehicle technician I normally have to do some jobs by feel looking at the top b pipe one in the pic I would say the bottom one is out about 1 to 2 threads and the top was about 5 threads
I can see the bottom one to be a arse to adjust

Even with all three closed there will be a variance in how many threads are showing.

Like was mentioned, the only way to know is to close them and count your turns out.

the hot hands only comes off the pisser red pipe that has a t-piece plastic connector which has a small part for the hot hands hose would that create an issue It looks abit like with clear pipe going up to hands



How could I turn it into duel cooling which pipes would I need to alter

Hard to tell what is feeding the hot hands. To run dual cooling you'll have to drill and tap another water fitting on your pump. If I'm not mistaken you can use the factory bilge line for your other cooling line. Theres lots of information on this subject right here on this site. Just search it

Yes I know was hard to get pic of the connector all it is was a biggish white T piece connector with bigger bore for the red water hoses and smaller one for the hot hands

I’ll take a look but don’t like the sound of tapping a water outlet may leave that alone

Tapping the pump is just drilling a hole, running a thread tap and adding a fitting. If your a Tech, this should not be an issue.

No it’s not an issue I’m more than capable I just don’t like messing with it too much that’s all
