the engine will run even on idle with intermittent hiccups and occasional smels like gas

I've been trying to figure this out for awhile (last 8k miles)

I have 34k on it

prior to spark plugs i seafoamed the intake via MAP sensor vac hose

and fuel via gas tank

I recently changed spark plugs

I also changed the airfilter

Not sure what else I could do or what he cause might be

when I start the bike up I get an fi but then it disappears after 4 seconds of running.

Any input would be appreciated I've bookmarked the forum and will be on often

Thank you in advance

 

Hey man I am having pretty much the same exact problem. I have a 2006 CBR600RR with 35k miles on it. Bike was running like a top then one day it started to idle uneven with little hiccups idling at about 13-14 Hundred rpms. Then as I ride for about 15-20 mins the bike starts to bog on the low rpms until I get it to about 4grand then runs like a top no problem taking the load. Also I cannot blib my throttle at all that’s how bad the bog is in low rpm. I did oil change oil filter and new air filter. Next I plan on checking plugs and TPS etc... just curious if you ever found a solution that may save me some time and or money. Thank you for your time.
