Just a curious question regarding engine and transmissions

[RayinHouston]

Hi Folks!


For example... The car Idles at 500RPM, but my Honda Motorcycle with a V4 has to idle at 1100rpm, and the rocket at 800... why Can't they idle lower? Is it something to do with heat or fuel consumption?

Hope that makes sense

What kind of V4 Honda are we talking about...??? back then, as now, you needed to run them at 1100-1400 RPM @ idle to keep a good oil supply to the cams....
