Not sure which part of the forum to put this, but I need to cut and shut some motorbike cams

Staggered firing. The crank is a cross plane so instead of having two up and two down (180 pairs) you have the journals arranged at 0 - 90 - 180 - 270. If the firing order is set to 1 - 3 - 2 - 4 the firing pattern looks like this
X--X-XX-X--X-XX-X--X-XX-X--X-XX-X--X-XX- or in a descriptive way it goes bang pause, bang pause, bang bang pause and so on.

The end result is that it has an engine sound like no other, similar to a V8 but not quite. If you have a Google for the sound of an M1 Yamaha it's that.

So I'm guessing you have a roller brng crank and you rephrased it.

Yes, convert the crank to cross plane, re-order the cams to suit and then get the ignition sorted for the new firing order and positions.

Millyard tig welded them

Depends what the cams are made of
