3. gear missing?

I am the owner of a 1972 mod. B GT 6 V. I have owned this bike for about a year and have restored the bike except for the engine. This summer
was the first time I had it on the road and gain some experince.The engine is going well but compare with other bikes I have driven the
change of gears seems very different. Its very loose when you shift from one gear to another. Is this normal on this bike?
But the main problem is that 3. gear is missing when I drive it on the
road. When the bike is standing on the stand and I start the engine, sometime I can find all the gears when I change from 1. gear to 5. gear.
Is there someone that have any idea what can be the fault? Do I
have to split the engine for repairing the gear system? Graitful for any answere that can give me any idea to tackle this problem.

It seems that the selector return spring should be broken.

You explain that the selector spring maybee has broken. Is it possible to change this from one of the sidecovers? Is there anyone that can tell
how to do it.

remove the right side cover. Remove the 4 M6 screws that hold the selector mechanism to the crankcase. The selector mechanism can then be removed. You may need to turn the gear shaft (select a gear) to get the toothed quadrant to clear the crankcase to remove it. Check the main spring is not broken. Also check the small spring inside the two indent dogs. To replace the mechanism you need to line up the two dots, one on the small gear that is on the end of the gear selector drum, and the other on the gear quadrant that's attached to the selector shaft. That's all there is to it. It's pretty straightforward.

3. gear missing

Hi Penguin 1957

Thank you so much for the answere, its gold for me. If I should get
problems, could you please give me your mail address. Then I had possibility to ask more. If something has broken, where to get parts
to this bike? Here in Norway Mv Agusta is very rare. My bike is as I
now the only one.
