shifting issues
« on: August 03, 2017, 06:23:31 AM »
Hi everybody.
My 77' CB750k as some issues when it comes to shift from 1st to 2nd. I need to wait low revs to correctly engaged 2nd.
I also have few problems above 2nd but rarely.

Do you guys have some clues? I am not familiar with gearbox.

Thanks.

Clutch cable properly adjusted?
What oil are you running?

Clutch was adjusted I can re do it.
Oil don't remember. Why oil is important?

Thanks

Many oils do not work well with our wet clutches.
