Topic: CB750 engine id #?????

[nickbee]

just picked up an engine from ebay that I'm looking to rebuld for a CB750.  The id# on the engine is:

CB750E-2310797

Can someone tell me what year and model type this came from.  The lister thought it was from a CB750F, but that's cause he mis-read the E as an F in the id #

Thanks!!!

unless i read the chart wrong it is a 1975 cb750K4.

Likewise, I read it as a K4 also.

thanks guys!!  where is this chart at?  I also remember reading that the F models had lower gearing for quciker starts.  Is this a mod that would be easy to do since I'm doing a complete re-build anyway?  What parts would be needed? 

Thanks!!!!
