Triumph / Royal Enfield 'Trifield' 500 trials - preparing to look inside the gearbox. 

As mentioned during the road test I took on this machine yesterday, I thought it would be a good idea to check the gearbox out and the owner agreed, so here we are. note - to all intents and purposes, the gearbox was empty of oil when I filled it having removed the drain plug first to 'make sure', but there was obviously some nasty crap still in there as seen here!
