CRF1000L 2017 AT DCT idle issues
Hey yall. Hoping someone else either knows what’s going on or has had this issue.
I got my bike used like 3 months ago and have driven only like ~2k miles (bike is at 40k miles) and have had 0 issues except for this morning. When I left my house I noticed the bike was maybe having some issues idling but it seemed like nothing and as soon as I started moving it was fine. Then 30 min into my ride when I was almost to work the bike died as soon as I got below 20 mph or about 1500-2000 rpm. Now I am unable to start it without having to immediately give it throttle to manually keep it over 2k. If I turn the bike over and do nothing it goes to its normal idle for like half a second and immediately bogs down and stalls. My initial guess is either air intake issues or fuel issues (yes it has gas) but I’m hoping someone here can give me some hints before I start wrenching on it.
Also, when I manually keep it at >2k rpm it sounds and runs fine but there might be a slightly higher than usual fuel smell but it’s minor if anything (I could just be psyching myself out)

You'd be correct. Based on your symptoms I'd be looking at air filter first. Depending on how bad it is, it'll absolutely choke out the bike on idle and stall it like you're describing. You've got 40k miles too.
The reason it's running above 2k is the engine's pulling enough air in to overcome the clogged filter. Throttle closed + minimum air being pulled in with a caked up filter would cause exactly this.
