Newbie here so be gentle lol

The gear selection was rough until I followed a guide about greasing the selectors under the battery tray which has helped but I suspect its the ball type mechanism under the gear lever that's worn or at least the arm off the side I, the gear lever has no springy Ness that helps it return to neutral, has any body a guide on how to change it or is it a bit of a stretch for a DIYer like myself.

If any of the terms I've used offend to describe my issue please feel free to correct me lol

Cheers in advance
