Restricting water before pissers

[fischer550]

I am running dual cooling, 2 inlets on the exhaust manifold, with a big bore 850 motor. I live in Colorado, and the water is cold now. It doesnt get super hot ever.

Out of both pissers, the water is barely warm. If I put restrictors right before the water exits out the pissers, it will make the engine run hotter? If so What size would you reccommend starting out on. I do not have a temp guage. I am also running a very tight restrictor before the pipe stinger.

Or should I just switch back to single cooling?

I run a simple valve att my hothands/pisser i Can then ajust too the engine temp i want. Remember that change engine afects carb settings.

I use the jetworks restrictor, comes with 3 different size derlin inserts to change out so you can tune water temp. also they make stick on temp strips you stick on head to get your temp right

Can inject more water into b-pipes etc and affect pipe tuning too.

this can be avoided by running parallel cooling, you can then tune engine and pipe temp independently.

Also good to note that in colder air temps the ski will require more fuel, as colder air is more dense

I put a piece of fuel line inside my cooling line just before pissers

Gotta have temp strips on the cyl head and pipe chamber. Jet maniac or maybe mcmaster-carr has them

Use the brass seat from a worn SBN needle and seat. You can drill it to any size you need. It will fit perfectly into cooling lines. I have sets of 2mm and 3mm that I used to run when I rode a lot in cold weather in NE. Then you just SS hose clamp them inside the line before the pisser outlet.

It's hard to tell but I'm set up I think just like you. I used 1/4in gate valves. They work amazing. I can adjust the flow to make the temp perfect. The one to the left is for my home made 'hot hands' and the one one the right is the one I use to control flow for temp. Hope this helps.

Sorry I got my left and right mixed up! Haha right is for hands and left is my flow control.

On a side note i dont varm my ski up on the trailer before going in, i starte it in the water soo cold water dont hit a hot cylinder. Dont know if it makes a diffrent but i think it makes sense
