    need HELP! 05 gpr

    I'm installing some riva heads on my ski and I'm not exactly sure on how to run the waterlines to the heads. I tried finding pictures of stage 2 skis but there was none with a clear shot of the engine that I could find. I bought the heads used last year and it didn't come with the fittings. If someone can post up a top view pic of how it's ran, I'd be totally grateful. Also, what efi settings would a gp1300r with a pretty much riva stage 2 kit be?

    a common water routing for 3 piece heads is to have #1 and 2 go into the exhaust manifold and dump #3 overboard. you can kinda see it in this pic. this is not my ski. it's flyboys

    heres a pic which is not pretty clear but close to what your asking, #1 &2 heads go to the pipe and #3 dump it overboard,
    the water fittings you can find them in a hardware store (brass)
    hope that helps..

    I had a similar experience.

    I like to use the permatex liquid thread sealer stuff.

    Thanks for the quick responses! So if I dump #3 overboard, does that mean I have to drill a hole for that blowsion valve (similar to the blue ski pictured), or is there a way to do it without drilling extra holes into the ski?

    if you remove your siphon tube then you can dump it overboard with the existing thru hull fitting. make it easy on yourself and just drill the hole. just make sure it's the right size.

    I just took a look at it, and yeah, it's a lot easier to just drill a hole and let it exit out the back. Any ideas on what setting the efi controller should be at? Thanks for all the help.
