[Shafer]

I just bought a 2007 ex250.

I got some service records with the sale and the following was just done:

New spark plugs - CR8HSA
Carburetor rebuild with new gaskets
Carburetor sync

.....the curent spark plug that was installed is the CR7HSA model not the preferred/correct CR8HSA.

I have two new CR8HSA.

If I install the CR8HSA plugs do I have to do and carburetor tuning, synchronization or idle settings?

Thanks for your help!
