Which Cam Gives 1-4 And 2-3 Firing Order

[Y2K81]

Came across a post where someone was talking about a set of cams that changed the firing order.

Hoping someone can point me in the right direction which ones they were. Thanks

Forgive my ignorance, but what would be the advantages of changing the firing order?

Unsure really. Exhaust note is different. Post had suggested it was more motogp style. It's also a thing the r1 did a few yrs back I believe.

Could be other power related reasons.

You'll have to get the crank to go with the cams.
The only guy that I know that has done such a project is Richard Stromboli at Attack Performance on a ZX-10.
