as above-all the comments already
ive managed to repair my gearbox,didnt take it out the bike to do it-ive only owned it for 5 months and not had one before either
the layshaft bearing is a cheap part so best to replace anyway
ive also had to get a kickstart pawl and a pin as the pin was broken and the pawl worn-otherwise its mostly a case of visually checking everything for wear or scoring
ive managed to do mine without any special tools,although the proper 2 pinned tool to undo the mainshaft nut( i think it was ) would have been handy-but as someone had already used a punch to undo it and its marked slightly already i didnt worry too much
just look at the postings and old brits and have a go-if it all goes wrong-which it shouldnt-you can buy a dvd by mick hemmings that will show you step by step how to check and rebuild it
