Hi All
After doing the Rupnow Vertical, I have had a thought, How would a twin look. I have done some drawings at 60 & 90 deg's. The 90 one would be simpler to mark out as every thing is at 90degs to each other.
What does every one think?

Cheers
Andrew

You are right 90 deg. Twin is a bit simpler for machining but i think
that 60deg. Twin is nicer.
I have question is there some advantage of 60 deg. twin opposite common
inline two cylinder engine?.
Ghosty sorry to interupt your thread .

Ghosty sorry to interupt your thread .

For small engines put putting say one hour over their hole life it does not matter ,but for motobikes the question has been resolved.
What is best ?
A 90 degree Ducatti,
something less Harley Davidson or a not at all old Triumpf.
Balance IS important and best in a 90 degree V2.
 
Anything that produces an uneven firing pattern within the 720 degrees is good in my books. Purely from a sound perspective.
 
Hi All,
Done a rough layup of the cam gearing, out by about 15thou(60deg). Will have to check cad drawings.

Cheers
Andrew
