Hi All

I'm trying ot plumb in my 2005 R1 motor using my Polo rad. I can't work out where to plumb the outlet from the oil cooler. It appears to go into a point near the bottom of the radiator. As I'm using a Polo radiator, the outlet form the oil cooler has to go into the top or bottom hose.

Any thoughts?

Here's a diagram from the Yamaha manual.

Thanks

I'd seen that. The later R1 looks different ( I had an earlier one)

Hi Wyn it goes into the bottom hose on a polo rad

cheers malc

Excellent

Thanks Malc

From memory (and that diagram) on the bike, water goes from the oil cooler outlet into the rad inlet side, through rad and back to the engine (cooled) via the bottom hose. So (and I don't like to disagree with Malc) it should go into the top hose on a Polo rad and return (cooled ) through the bottom hose.

There's a flow diagram in the R1 manual as well as the one you've shown.

I was just thinking i'd done mine wrong, but if it goes into the botton hose it will bypass the rad.
but malc does know his stuff

here's what i've done

This is the best view I've got of my setup.

It doesn't go in either the top or bottom hose on the bike. the attached picture shows that it goes into the rad at the same level, but the opposite side from the bottom hose / outlet to the pump. So it does get some cooling through the rad.

And here's the bottom hose exiting the rad.

...which is the inlet side of the rad...as I thought/said. ;-)

Thanks Guys

I got confused by the bike connecting to the bottom of the intake side of the rad!

I'll connect it to the top hose - it's a little bit more difficult but not a huge problem! Shame I've already prepared the bottom ali pipe (drilled a hole!) for the additional input.
