Cooling Line restrictor

[Bobert540]

Just wondering where you guys are getting/making your restrictors. I need a 4mm restrictor. Is there anything at a hardware store I could use? Sorry having a brain fart and figured I would see what everyone else was using. Thanks!

I've used a 1/8 brass pipe plug, the type that uses an Allen wrench . Just drill through the center, 3 mm might be just right in the winter.

I use the Jetworks quick-disconnect restrictor. It comes with three different sized inserts (2, 3, 4mm) and you can run without restrictors - so four sizes total. Changing sizes takes only a few seconds.

that's an awesome idea. How much are they matt?

 

[Matt_E]

Looks like it's $21.95 for the 1/4" and $25.95 for the 3/8".

Extra bonus, take the 2mm pill and jb weld it to your stinger fitting.

I have dual cooling and in the winter time here I use 2 carb Mikuni brass "seats" that are drilled out to 3mm and then I just hose clamp them in the lines exiting the head. Those seats are the perfet size to slide inside water line.

Ive never seen those JEtworks ones. nice!

I need the 2 mm for winter riding.

You can find 3/8-inch or 10mm diameter nylon standoffs at any local hardware store that can be installed inside the cooling hose right before the pissers fittings and they come in different hole sizes.

I use a little piece of fuel line, it fits perfect in the cooling line

 

[luker]

oem fuel hose is 4 mm diameter works sweet

Both of them?

 

[Matt_E]

Yes. See the pic, I use two head outlets.

You can drill a 10mm hole is just about anything.

10mm ain't much of a restrictor.

 

[Dustin Mustangs]

Actually I would call that an expander.

10mm ain't much of a restrictor.

10mm is just a little larger than the 3/8-inch hose inside diameter.

Just about anything you can fit snug into the hose with a hole drilled through it will work.
