So, I recently changed the oil and noticed some smell of gas when I was recycling the old. Put new oil in, slight gas smell (maybe burnt) from the crankcase now as well. Could simply be the new map I loaded which needs to be leaned out a little.
However, while looking around at what may be the cause, I noticed that at idle, the temp of my #1 cylinder was about 50-80 degrees cooler (Farenheit; about a 20 degree for you advanced Celcius folk) than the other three. Now, I realize that an IR gun on shiny pipes isn't the most accurate, but after many (hundreds? ) of measurements, this seems to be about the average discrepancy. The rest have an insignificant difference from each other. If I ride for awhile, stop and kill the engine and measure, temps are all about the same.#1 and #4 may be a little cooler, guessing airflow helps there.
Pulled all the plugs (iridiums, changed 2K ago) and all look normal with a nice light tan color.
At idle, the tach is dead on. If I hold at a given RPM, the needle bounces just above and below the mark I'm holding. Nothing major, about the width of the needle.
So, my question is, is this potentially a misfire in the #1 cylinder? I'm not confident enough in my mechanical ear to know for sure what I am hearing vs. what I should be. If you've seen my posts, I chase my share of phantom gremlins. :banghead:
I hate taking it to the dealer because of the time, money, and frankly the attitude I get at the local shops. If I have to, I'll do it, but I'd like to get some input and some other checks before I do.
Next step I guess would be to pull the boots one at a time and see if the #1 doesn't change engine noise? Then, maybe switching the coils (can I just switch the wires from plug to plug) to chase down the electrical side?
When I did my first TB sync way back when, I did move #1 on accident, but tried to move in to original and nonetheless balanced them all. Maybe that has something to do with this...
If anyone has some advice before I take it in or continue the proverbial chase, I'd appreciate it, as always.

P.S. Link to a video from another post. If you ignore the 6K revs, you can hear the idle.
