any reason to stop at 5? i would think a 6 cylinder would be only slightly more work?
pretty cool project!

Cross-plane, like an R1 ?  Please be sure to post an audio file of it running when you finish it....

While intetesting, I'm not so sure having 4 throws at 180 and the 5th at an obscure angle will work out with regard to balance.

What are your plans to valance the assembly?

Do you have a plan for line boring the mains? While a AR inserted may keep them close, I can't imagine they will remain close after welding.
Any day on a motorcycle like this that ends just needing parts and labor is a good day.

Yes I will line boring the mains, one main is little out, but I will fix it. I think balancing will not be a problem, I will use bob weights maybe. This is a prototype engine and maybe it will run late 2018, I dont now  :wink:

Looks like it came from the factory like a 5 cylinder and I mean that as a compliment!
Good work
Have a Harley, spent lots of money on it, thought I had a fast motorcycle, bought a Busa, realized all I had was a fast Harley, not a fast motorcycle!

Brilliant :)
how did you connect the oil gallerys ? plug and external connection or internal sleeve or something else ?

and have you normalised after welding ?

Very neat. What will you eventually be using to provide fuel and spark for this engine?
