Oil pressure switch

<< < (2/3) > >>

Sorry for the confusion, meant switch not gauge... right now running as up to 93c instead of 80c spec, so definitely hot but dont know what is the pressure. Plan is to follow Steff rec to change the switch. If still red light, than i suspect the pressure gauge can help but i would first need to change oil spec for more visco like 15w40. Ishouldnt run on red light with a new switch.
Thanks

I change my damaged oil presure switch with one from a Honda CBR929..it is the same thing..also i think it will work a cbr954 oil switch!

Mihai, when you say damaged did you get the light coming up after oil heating up or was is some other symptoms. I have checked ebay and found genuine honda switch but it says superseeding the #300.... original

The actual ref starting with 300 are actually rather expensive:(

Which model did you choose?

Thanks

My oil switch was loosing oil...a lot!!!
I found some oil near my bike and when i took of the sprocket cover it drained about 2-300ml of oil!!!

The porblem was that the sealing from the top was damaged and all the oil was comming out from there.

I don`t know the model but in the service there was a Honda CBR929 with the engine off and we tried the oil switch from the CBR and it was perfect!!!
I still got the CBR oil switch on my CB550k.

It s like this one:
