How long will the ceramic bearings last in general before they need replacing?
What size are the main and front bearing?
Do the M21 engines use a specific conrod or can you use a Picco conrod?
Can i use o'donnell plugs in the M21?
The full ceramic version spools up faster than the standard version. The regular M21 spools up fast enough for me though.
The M21 uses the same Picco con rod.
I have not used O'donnell plugs personally in the M21, but they should work well. They work well in my other engines when I have tried them.
