Rat Bike Project

I was looking up some youtube videos last night on fans and some interesting stuff there. One mob were doing a lot of comparisons of temperatures before and after adding fans in different situations. They seemed to do the job ok. They found the highest rear cylinder temperature without fans was out on the highway with the engine working hard. Even though they were going fast, the rear cylinder wan't getting much cooling air.

Intuitively yes, But airflow around bike engines is complex and sometimes Oil from the seat area  ends up well forward. The front Cylinder on a Vee twin works the Hardest and usually has the Bluer Pipe. Any idea Why?   I like V twins , There's a LOT right about them for a Bike AND a small Plane.Nev

I love flat twins and Guzzi V twins.

 

Others not so much.  But do appreciate a high performance twin sport bike.

 

I am resisting the cruiser v twins until my back wont allow sport riding.

 

You still riding Nev ?

Interesting, I thought most v twins would have too much vibration for a plane - I know mine would!

Mind you a purpose built one like the Spirit might be less like a washing machine.
