Hi,
I'm just about to fit an inline Radiator Fan Switch, but looking on the CBS website you need to now the temperature they should cut in at and cut off.

Therefore please could some advise me what cut in/cut off temperatures are suitable for a 919 Fireblade engine setup.

Thanks,
Iain

IIRC for my Pinto engine I went through the Haynes to find the switching temps for that, then found a VW switch of the same temps to fit my Polo rad.

cheers,

I think the 919 runs best at about 90 degrees?

If you've got a VW rad, then the VW switch will do the job.

The item I use switches on at 90c, and off at 82c. One of them I had was on at 98c and off at 88c, just can't recall which VW it came from.

I've got the wiring diagram somewhere.

Cheers,
Nev.
