Well it seems like my bike has, like a few others just lost 5th gear.

I've read up and searched with lots of hits but I want to best guess the problem parts.

I'm overseas and I wont be able to work on the bike for a few months, so in that time I want to order the parts I will alkmost certainly need.

If I wait until I get home and then get into the engine it will take a few weeks for parts to arrive, then its time for me to leave again.

Guessing I need:
5 gear cog
Selector Fork / Forks
Any other likely culprits?
From what I understand the drums have not been a problem

Maybe a 2nd hand gearbox?

Time to split the cases. The dogs on fifth gear have been rounded off.

and more likely the mate... if one is worn, there is a almost 100% chance the mate is worn too.:thumbsup:

Fifth and third gears both probably need replacement. I just did it because of a lost third and fifth was toast too.
