Howdy, What is typical cold start up oil pressure suppose to be on an F1. I am starting up in warm summer weather with 15/40 oil and seeing near 100psi at fast idle/2K rpm. That seems really high? |

I too have been wondering, but between the classic meetings at Spa and the IOM TT you might not get a reply for a wee while. |

Hi cal, what does it drop to when hot? I keep hearing 10psi for every 1000 rpm. Though that's car people telling me this. The epicycle twin had 145psi at 3000 rpm. With a lot off playing with springs and preload I've got it to 50psi at 3000rpm cold. When it's hot it's 25psi at 3000rpm. That's with 15w-40 oil. That's my take on it. Boucher. |

Thanx.....I dont know what it drops to when fully hot and at operational speed/rpm yet. I am just getting it running and I have not been able to get any real shake down runs in yet where it is fully hot. Had it running in the garage a few times and gone down the street once just far enough to check the gear box and clutch for operation. |

100psi. at cold start isn't unusual. It will drop as the engine warms and will run about 35-40 when hot, 60-70 at high revs. All of the engines I've seen in good condition run about the same pressures from an 85 F1 to aq 1100 Multistrada. |
