Wear on 5th gear
Found this old post of what i did. You are welcome to ask questions if you need.

That modification has done 10867 km and has been completely successful.
This was about making 5th gear last. As you will see, it became about how to stop 5th gear destroying the engine.
The gears are wider. That is why they last. You will have to grind both original 2nd gears to accommodate the 3yf gears. (There is no detriment to 2nd gear, only material is taken at centre boss of small gear pressed on shaft, and a lick off the big 2nd gear)
You will need a small press. No heat please. No change to 3yf gears, fit straight in with mod to 2nd gears.
I believe the factory changed the main engine housing to fit wider gears.
Quote: "The best (cheapest) way for me would be only replace 5th gear on the input shaft, since the gear on the output has no visual pitting at all."
'Best' and 'cheapest' are not words can put together any place i know of
Depends what you need from the bike.
Cheers,
