I have a 2002 TTR250, starts up fine but when I give it throttle and the rpms settle down, it does this weird vibration/rattling like it has an air leak and the rpms kinda go up a little. Anyone experienced this before? Here is a link to a video I took. https://share.icloud.com/photos/03dsY_k6vXv6i-TH3XDZbSp1g Also on WOT, there is a ton of black smoke so I’m sure that is a separate main jet issue right? Thank you
