i have discover the center exhaust valve can have two different numbers :
12005-1157
Partzilla say it will fit E1 E2 E3 E4 E5 E6 and name it "VALVE-EXHAUST,CENTER"
and
12005-1115
Partzilla say it will fit E1 E2 and name it "VALVE-EXHAUST,MAIN"
but if i look on an OEM catalog
( E5) http://www.kawasakipartshouse.com/oempa ... d-cylinder
(E1) http://www.kawasakipartshouse.com/oempa ... d-cylinder
I can see it is the same part , on the second link (E1)i see the two number with the same name "
VALVE-EXHAUST,CENTER"
Could someone explain to me why is there two differents number for the same part?
Thank you
