Sounds about right to me. Not sure how different the 07 is but on my 06 R1 I did pretty much the same. Does the 07 have an oil cooler? An outlet at the front of the motor? I tied this into the line that goes from the thermostat to the top of the rad as it is hot water from the water to oil cooler. Do you have an expansion tank, if not you'll likely struggle to get the air out. top was teed to the radiator overflow (and small thermostat bypass) and bottom teed into main return from the bottom of the rad before it returns to the lower left of the engine.
Here's how I did mine http://www.locostusa.com/forums/viewtop ... 1&start=45
Hope you get it sorted out.
Yes, I have the tank - it came with the R1 radiator that I'm using.
And yes, it does have an oil cooler. The radiator has an outlet for that too - that's where I plugged that.
