This was  a common problem on the early bikes. The shift drum has a set of squiggly grooves machined into it that the shift forks ride in to move the gears back and forth. The problem is that there is a pointed section or high spot on the drum where 2nd gear engages and this point breaks away from the drum and makes the groove too wide to hold the shift fork in position, alloying the gears to disengage.
You will need a new shift drum, probably a fork and possibly second gear and pinion.
