You are just feeding more carbon too it. 99% of the oil falls out oil in the air from vent gas.
It does run down and give that impression.

Front side of throttle body is clean. Behind back side is from the charge left from the fuel injection left in intake when you cut it off. What you are saying is tin man BS.

I add Techron for the first fill-up of the season in all my bikes. I think it's beneficial for bikes that sit in storage for four to six months.

Some years back BMW did extensive testing of fuel system additives / cleaners and found that most did not clean fuel injectors. This
is one of the few that did but be careful - using more than one ounce per gallon may harm your O2 sensors. I buy the larger auto size
and use it twice a year - CA gasoline is the worst imo.

Put it on a clean cotton towel, and carefully clean around the butterfly. Just a tad on the pintle valve tip.

Never ever put anything in fuel tank except gas. Unless it sits over a year. Then only enough carefully measured for a full tank of gas which also should be in there. An FI system from tank to fuel injectors is totally sealed. and will never dry out.
Ok so the bike sat for about 2 years I drained the gas put brand new premium gas and brand new battery in it and it starts up but sound like it's running lean and is giving me codes for map sensor and o2 sensors. Is there anything I can clean the map sensor with without having to remove it completely its held in place by a peice I dont want to remove( it holds the throttle cables.)

I've used this - Gumout - without it creating any problems / codes -
