Hi lads,

The intention there is more to put my head on a warm shoulder...

I closed the gearbox after a deep clean of any part, change of the seals and the bearings, everything seemed fine, but when closed, the gears are not willing to pass smoothly...

I have absolutely no clue of where it might come from but this is everything but smooth...

I bought this bike years ago and I never ran it so I don't know if there is an issue from the beginning but the gears are clean and fine, the forks seem right, the drum is in very good condition.....

Tomorrow, I'll open again and try to figure out the issue, is there anything to check? a classic failure ?

Thx

The gears require the shafts to be turning to shift them.
When the bike is together, motor not running it requires some rocking fore and aft to run the box up and down from 1st to 5th and back to 1st.
 
Classic mistake is there not adjusted


Inspect springs and that the shift axle is not bent . Last time I got a brand new one from Heiden Tuning
It was not at 90 Degrees had to give it a hit with the hammer in the vice before it went in behind the indexing star wheel.

I did that rocking and one of my lead was indeed that the GB requires more speed than just my hand to let me pass the gears...

Another one was that I found after the whole reassembly a washer identical to the one at the end of a shaft (the hollow one with the clutch rod inside)...
I wondered whether they might adjust the lash at assembly with two of those washers instead of one...??

I like the answer of Signal, i'll try that.

Thanks Jan-P !

I spent some times on this screw to adjust the tiny gap I have but it never moved...

Thanks for the vids, I will keep working on it so.
 
Thats the same assembly lube I use :thumbsup: You will want to change your oil pretty quick, It can cause clutch slipping if left in the motor for very long.
do you advise installing the old discs, running a bit, and changing the discs for the new ones at the first oil change ?

Does it contaminate the discs or is it just a pb when the lube is inside and as soon as you take it off, everything comes back to normal?

I've never felt that it contaminated the fiber discs, I ran it a little longer than I should have in a Triumph T140 750cc. The clutch started slipping so I changed the oil and it went back to normal, no harm no foul. I'd ride it a few times, change the oil and forget about it.
