Answer
First of all this is not a question about a Honda CBX, so not my area of expertise.  However I am familiar with this type of problem.  It sounds like a selector fork in your transmission is either worn or bent.  This is an expensive problem to fix, since it will require engine stripdown.  Treat the bike gently and change the oil, see if you can find any metallic powder in the old oil when you change it; there is no magic easy solution, sorry.

Good luck,  Jan
