Info a bit limited, you can look for a original frame, or Paugcho make a frame to accept a later model transmission. Built one awhile back and it was a solid frame, everything lined up good.

There are also 4 speed gearsets for WL cases and complete gearboxes coming out of Europe. See Samwell Supplies.

Why don't you want a regular 45 three speed? They work just fine.

Perhaps, but how do you reconcile that with the 41 tooth 45 rear sprocket versus the 51 on a Big twin? That is why the 45 has that ratio. Now if running a 51 tooth rear wheel it all changes.

Since you appear to have a compulsion to find fault with anything I post, in future I will wait patiently for you to make the definitive remarks on every subject.
Perhaps you might revisit "arithmetic" with regard to ratios since the subject is confusing to you.

Not a bit confusing to me. You like to post without any basis for your comments. I merely try to get you to follow through with information for those asking. I am not the one questioning the "How to". But your lack of help to those asking by your "I know it all, I wrote the book" BS helps no one. Get over yourself and actually answer the question as asked. It might actually help someone.
Or do what you always do and delete your post which helps no one.

Please explain why you want to do this, building a bike from parts is an expensive proposition, if you explain your motivation we can advise.
Two experts with lots of knowledge replied, it would help everyone if you explained your motivation.

If I were you...I wouldn't use a rare engine in a custom build..
If a chopper/ bobber/ thingy is your goal, use a more common (later) G engine instead.
Swap your engine with someone who's looking for a genuine 42WLA engine for that rare type 1 build...

But that's me...what do I know?

@Robbie; the european 4-speeds for a WL is all about adding another gear to the standard box...endratio is the same..it just 'solves' the gap between second and third.
