You would need to use the nc21/24 electrics (loom, cdi, coils etc) to work with the 21/24 engine and vice versa.

You also have big problems with the exhaust fitment too - the NC30 is paired front and rear. The NC21/24 is paired left and right.

What are you planning? Give us a clue!

Swap all of the electrics as well as the engines.

They are all NC13E based engines so the engine cases are the same, they are just mounted in different places.

The NC21/24 oil pipes won't line up along the NC30 frame. The NC24 uses more coils so you will have to make brakets and holders for things.

There is a member on here with an NC24 engine in an NC30 frame.

Not difficult at all but if you dont have a clue about electrics and thinking then don't bother.

The biggest downfall is the exhausts.

The NC2x uses a 4 - 1 collectorbox, or if you have the HRC system a left/right split due to the cylinders firing order

The NC30 uses a front / rear split.

Putting the NC24 collector on the NC30 engine should be ok.

Putting the NC30 ehxuast on the NC24 engine wil loose some perfoamcne as the gasses will be off balance

You cannot fit the NC24 exhaust in the NC30 frame.
