My guess is the gear dogs are worn,you can get them back cut at a machine shop,for half the price of new gears,if you can still get them.
What's happening is ,as the power comes on, the gears want to spread apart,because the gear dogs have worn a ramp,so as to speak.
Take them to a machine shop,get them to back cut the dogs a little and you will be good to go.
Or your shift forks are getting worn.But my guess would be worn dogs.
Cheers,
Steve.

Good advice.
Before you pull the engine apart check the gear change mechanism that lives inside the clutch cover.

Definatly not a clutch issue.

Check out items 2,3,4,5,24,26,27,28.




Check items 1,2, and 3.

Number 14 is a plastic spacer that fits next to the gear lever and stops the change shaft moving too far. It may be missing and cause poor shifting between gears.
