Gents,
Can anyone tell me what the difference is between an E-1 and an E-2 cylinder head for the KX500? My 95 K5 has an E-1 head, but I just saw a 92 K5 head that was an E-2 head. I assumed that an E-2 head was a later casting update, but now I'm not so sure.
Can anyone shed some light on the situation?
Thanks!
