I have just brought my first motorbike, And it is a Jawa CZ175 Trail 1976. I do not know much about the bike. I was told it was a automatic gear box (which I did not want, but brought the bike anyway) And as I am new to the motorbike world I did not ask questions really as I only paid $260NZD for it. How does the gear system work on this bike as it does have a clutch etc. I am going to be pulling it apart and cleaning it thoroughly as I am currently pregnant and have brought it to do up while I await the birth of my son. Any help will be great in comments tips and advice!!
