Okay, this IS a really decent thing going here and LOTS of info available.
Now, I've seen some CBX stuff, but don't remember if it was for the 80' or not and I could use some of that, in a service manual. I could also use some Kawasaki GPZ1100 Service manuals as well. I HAVE places to find the Parts info, just don't have the Service manuals for the particulars of these bikes. I DID see some stuff on other GPZ models, but not on the 83' GPZ1100. Also looking for a CB77 Service manual, got access to parts manual on that one as well.
Bet no one has anything on a Jawa250cc model 590! I could use a service manual AND parts as well.
BTW, I am AMAZED at the amount of info that has been shared here, although I don't know WHY I'm amazed,after all, This IS the SOHC4, RIGHT?
