Hi guys, first time here on the site, I apologise if you have already discussed this. I am riding a 2003 Z1000 and I cant change into first gear. The gear lever just clicks and clicks, but I cant get down from 2nd. I can go up, no problem, but not down. What has happened in the gear box? Is this something that will be a major repair? If possible I would like to fix it myself.
Have you tried adjusting the play in the clutch lever? I had an issue on mine where the clutch lever adjuster got cross threaded and wouldn’t tighten up enough to fully disengage the clutch while shifting.
First , verify that the actual shift lever down at your foot isn't hitting something, Like the frame or a bracket or something. Sometimes just changing the position of the lever will fix things.
Otherwise it could be the shift spring inside the clutch cover has broken. You would need to open it up to look. Not hugely difficult to change.
