So I have an 04 Ninja 250R and it was driving fine. I love the bike. But then one night while I was riding home it started (almost put of nowhere) bogging down and shutting off. It also idles at about 3000-4000 rpms right when it is started. I have read all kinds of posts about issues similar but they all have the same solutions. I have already cleaned the carbs and replaced the spark plugs. Any suggestions would be great. I posted a video on YouTube and will put the link on here when it is up.
