### ⭐⭐⭐⭐⭐ Wicked Stuff!
*by F***E on 30 April 2017*

This is gearbox magic. I race my Honda DC2 way too regularly :) and far too aggressively if I'm honest. It used to have a 3rd gear synchro crunch and after doing a fluid change and adding this magic stuff it's totally cured it (18 months in) still no crunch. The box and gear changes are brilliant
