That's a bummer 'Mo. Always crap when a seller doesn't tell you the full story.
Worth somebody else chipping in here but you can check the shifter mechanism without separating the crank-cases (you just have to take off clutch cover) See diagrams for things to check like the shifter shaft mechanism 1 and springs 2 &3 in top diagram attached. ( and profiled shift plate and pins on the end of the shift drum plus the two spings 3 & 12 and associated roller mech 11. Also the spring loaded pin 9 that is mounted in the top crankcase and runs in the guides of the shifter drum. (possibly the 1st thing to check I guess before removing clutch cover etc) . Other than that you would have to check the shift forks and drum, which means removing the bottom crankcase. On the bomber the crank is totally different to most other Hondas of the period and later, in that the crank has pillar blocks mounted in the top case .... so splitting the cases (with top end undisturbed) is not too daunting ... albeit a pain in the ar*e seeing as you bought a supposedly restored bike. I feel you pain.
Perhaps someone else can chip in and confirm what I am saying ... Bryan/RoyHalliwell etc.
