Detent spring or something else?

A gear change issue has developed with my old Yam RS125DX. Sometimes (maybe once every 10 times) when I try to change down from third to second I can't. The gear lever just bottoms out without changing gear. The solution is to quickly change up to fourth then back down again. It only ever does this changing down, from third to second. I'm aware of the detent spring, if it's weak it can cause this type of problem. If I operate the gear lever by hand the spring feels good, if feels strong. I changed the gearbox oil to correct spec after this developed, this hasn't solved it.


Any ideas on this?

Funnily enough I fixed a fridge with a hammer last week but in this case I wouldn't know whether to whack the gear lever or in the general area of the detent spring.
