Had an issue last weak where the bike wouldn't idle at all, bogged heavy. Ran perfectly fine before, so we figured it was just a messy carb. Took the float drain off and the pilot fell out with it pinch so we installed that, started up, and now the idle is climbing and hanging. It starts with the choke on, then once it's off it slowly builds. Oddly enough I did a quick Google search and came across 2 other instances where guys with yz125s had a bogging pilot issue, cleaned it/replaced it, then suddenly had the building idle appear.

Will check float height haha wink

Pull the pilot jet and clean it.
