CB72L rotor in my 64 CB77

Post by Jlovvorn » Mon Feb 27, 2012 9:21 pm

Is it normal that my CB77 has a rotor marked CB72L?

And even if it is, should I replace it with a standard output model?

The reason I ask is my bike is dying after 15 mins of riding with light on.

I have searched on the forum, but not seen a definitive answer on whether having this CB72 part in my CB77 is stock and/or acceptable.

The rotor for the CB/CL72/77 will show CB72 or CB72(L). ........................lm

My CA77 rotor says CB72 on it and so does the rotor from my spare CA77-E motor.

Is there a functional difference?

Are the timing marks the same?
