What Is A "Normal" Cylinder Head Temperature Range?

<< < (2/2)

Sorry but i fail to see how an air cooled AIRCRAFT engine relates to a motorcycle engine. Air craft's go up in 10's of thousands of feet, and higher up in elevation air quality goes down. Motorcycle engine's maybe a couple hundred feet if that..... alot more air on the ground. I just fail to see the connection is all .... but your probably right, only thing i can think of is what is the melting point for the materials used to make the head. And stay plenty far away from that point lol.

I specified aircraft because that is what I know.  Perhaps that info is of no use.  Sorry.

WTF304:
It's not useless info ... just hard for me to find the relation to apply that to a motorcycle. ... with all the variables given. Those airplane engines ... are they cast or aluminum?  ... if they are aluminum then i can see that being if not spot on damn close.

I took a run last night and payed attention to the temp, it didn't go beyond 280 while running the highway. Once she starts getting to 300 and it will at a stand still she runs like she's getting too hot but that could all be from my jetting. Curious to try a colder plug if i could cross it to one and see what temp i get and how it runs. A good combo of sprockets for highway use for me and my area is a 16t front and a 40 rear.
