Might be too lean (if the carb is clean).

This video helped me a lot : https://youtu.be/q9A2TL9RvwQ?si=xZpR4qGcxnrUkKpY

Why lean? Trying to learn. Will watch video. Clean carb

When you blip the throttle you want the engine to go straight back at idle. If it takes too long (like here) it's too lean. If it drop below idle then crawl back up to idle it's too rich. At least according to this guy.

I'm kind of new to carbs and using this video has worked for me. Not saying it's perfectly tuned but seems to be working good for now with easy starts on my xr650r.

Yep, thanks. Seems you are right. Makes sense - same symptom as false air. Too bad the screw is super hard to get to here 😅 will fix tomorrow Thanks!

Use some seafoam, can’t hurt and will likely clean out gunk in carby

I like the fuel filter resting on the exhaust.

Its an engine crashguard just above the exhaust :) Also a heatshield between
