Spark plugs NKG B_4
 

I have a 1650. I want to change the spark plug. However the CC dealer can't find the plug I need anywhere. The plug is NGK B-4 I will continue searching this forum. It's hard to navigate on a cell phone when your old and shaking

Start checking with auto parts suppliers.
Many of them carry a full line NGK plugs, chances are the plugs you want will
have to be shipped to you.

Just Google NGK B-4,
