Default Re: Making a custom bike engine

In a 6V there are two different firing orders, odd and even. odd gives a lumpier sounding motor, even is more common for the same reason, it gives a smoother idle.
Looking it up there are two. 145 235.
and the Porshe uses 162 435.
The crank discs need to give max primary compression, and as, If they are split cases?, that gives problems to recessing the crank for seals and bearings.
if bolt together segments, crank discs could be recessed as a bike engine crank is.
