Grandpa taught me to ride as a squirt, when he passed I kept his bike going for many years and had many fond memories. LT125s are in fact indestructible.
Noticed the same on my 300 KQ, could be the adjustment of the shoe ratcheting mechanism, or just master cylinder issues. My solution is ditch drums altogether.
I never use gps while riding just because there is something about getting lost in the woods on a bike that lets you escape from the world for a bit. Obviously don't get lost literally haha.
