So its a bigpin 750 with a 650 westcoast pipe. Stock head thats cut to give it around 180lbs. Im a yamaha guy and not sure if these do fangled kawi's like their water routed differently. What do you guys think of what im thinkin:

2 inlets to two fittings on each half of the exhaust manifold.

2 outlets on head. Stock outlet goes to the top of the pipe. 2nd outlet to a pisser.

Hose from rear of pipe (rearmost fitting, it's on the elbow part) to the stinger fitting, with a T fitting to a 2nd pisser

or if you only have one cooling line, only have the stock outlet on the head.

What he means is on the exhaust manifold, you had a choice of one 1/2" inlet as you have diagramed or two inlets at each end of the same manifold. You probably have them plugged off. Run your two inlet waters to these 3/8" fittings.

Being you only have one outlet on the head, run that into the front fitting of the pipe just above the the exhaust manifold. Then run the back fitting of the headpipe(where it make the 180°) and run that to the stinger as suggested here with a T running out the side. That is the way I did mine on my 750.

Here's what I mean. any questions?

Please ignore the number of plug wires....

He has an extra fitting that yours does not. Mine has the same extra fitting below the head pipe. (see my recent thread about water injection on wesstcoast pipe)

I would route it like this

put up a picture. I believe the second hole should be for water injection (as I have heard, no experience to speak of) and it may hurt your performance to run a constant stream of water in there.
