58 A10 hard shifting
« on: 22.04. 2011 23:00 »
My 58 A10 really shifts hard,not just when running.The shift leaver itself moves hard.Now this bike has sat for 20 years.Is there anything to look for?It definately is not a smooth shifting bike.

Change the oil in the gearbox.
Remove the detent spring ( under the gearbox) and clean out the cup it sits in.
A lot of crud can build up in there stopping it from moving & I have seen some just about solid rust.
If the box has been dry for a long time you can also get rust or crud preventing the rollers on the ends of the shift forks rolling which will make the shifting hard.
A dragging clutch will do the same thing

Trevor,
                  Rollers on the shift forks?
I think maybe you are thinking Triumph!

No trumpets in my shed but probably too many different examples of Small Heath's finest .
Then again there was the 6 XJ's ,2 SR's & R75 ( Work fleet ) that have loose parts rolling around in my noggin.
Always happy to be corrected.
