Thank you for the video! Our TTR had the same issue. Followed your video and instructions, got a 17.5 pilot jet, drilled out that idle screw and its running great again.
Yeah, sounds like it’s the same issue I was having, either a clogged pilot or dirty carb or both. Pull the carb apart make sure it’s clean make sure that pilot jet you can see through it and while you’re in there, I would bump it up to a 15 or 17.5
