If it’s the seal behind the front sprocket it’s a stepped seal. Only way to replace is to split the cases.

Start with the gear shift shaft seal, that’s a 20 minute job. I found that you can replace without draining the oil if you lean the bike over against a tree or something solid.

Hopefully it’s the easy fix ie gearbox shift shaft seal 😁 Searched and found part number for the split seal and David Silvers can supply 👍
