What should the water temp. be?? And where abouts would you expect the temp guage to be for normal road driving??

ian i get no more than about 80 degrees never seen it higher - i do think sometimes i dont believe the guage - i would expect to see more

Mine is 70 on the road an 90-95 on the Ring.

Not sure about the temp but mine runs just under half way on the standard hayabusa gauge.

a Hayabusa should run between 80-90 Deg C normally. if you are using the genuine fan switch it will bring the fan on at 106 Deg C and switch off at 99 Deg C. if you are using the Suzuki speedo, the temperature gauge needle will be smack in the middle when running normally.

Excellent. Water temp on the exit of the radiator is a steady 70-71 and the Busa temp gauge is a needles width under half way.

Need to turn the fan switch up a bit though as mines set at 85. Didnt realise that the standard switch came on that high so Ill run it up to 95. (Using a Revotec unit, not the Suzuki switch).

Thanks peeps!
