Hi!
I'm Gustavo from Argentina.
I´ve recently acquired a CBR400RR NC23 J for a restoration. I'm rebuilding the engine, and I found that it has two EXHAUST CAMSHAFTS!!! I've been looking around and it seems that they are both the same tho, can anyone corroborate this?
Evene if they are, I´m missing a timing mark, been trying to find a valve timing diagram with no luck. Does anybody have one, or can give any info on the subject?

I Would get the INTAKE camshaft if I could, but this bike is pretty uncommon here, so buying one from another country is going to be a last resort.

Thanks you!

PS: sorry for my lousy english, we speak spanish here LOL!
