So I've been chasing this intermittent issue where my bike will sometimes lose power, bog down and refuse to idle when fully warmed up. I can't replicate it on command - some days it'll happen, some days it's fine. I can still ride it, but it's clearly down on power and it constantly needs throttle to prevent it from dying.
What I notice is that the clean side of my airbox collects quite a bit of oil. I rode in to work this morning and it bogged down. I opened the airbox and used a couple rags to remove the oil from the airbox. There wasn't a lot, but the entire airbox is covered in a fine oily film.
Anyhoo, after cleaning the airbox and reinstalling the (brand new) air filter, I started the bike and it magically settled into a perfect idle.
What the hell?
What I'm thinking is that my crankcase is spitting out too much oil and an excessive amount of warm oil vapors get into the intake when the engine is fully up to operating temp.
Thinking of disconnecting the crankcase breather hose from the airbox, plugging the hole in the airbox and going for a ride to see if it helps.
Bad idea?
