I need some opinions as to what this might be pointing to, if there's a problem with injectors or valve clearance or more serious or maybe nothing.
It all started when I noticed oil residue (Pic #1) under exhaust header #1. I didn't even know this port? hole? relief spot? even existed. What is it's function?
I investigated the other cylinders (Pic #2) and they were all fine/clean.
Upon opening the airbox, I noticed more than usual residue built up near cylinder #1 (Pic #3). I'm assuming this might be because of the angle the bike sits when on the stand? I know a little residue in the airbox is normal, but is this too much?
While removing the plugs, I noticed plugs #1 and #2 came out with almost no resistance (unthreaded or removed by hand alone). Removing plugs #3 and #4 seemed more normal with the initial breaking loose and removing by hand.
As you can see (Pic #4) these plugs do not have many miles on them (3,900 miles). Plugs #1 and #2 came out with a wet fuel around the threads (tips clean and dry). Plug #3, WHAT THE HELL IS THAT? Carbon? Blowback? And finally plug #4 had a wet oil residue around the collar and threads (tip dry).
The changes from last plug change at 11,500 miles is the custom mapping and the removal of the PAIR valve system. According to the Dyno operator, my bike was incredibly rich throughout the entire RPM range (notice the 11,500 mile plugs). So he leaned out the bike. So why don't the plugs look lighter? I also have ran the bike pretty hard with the custom mapping and the 2 days at Grattan. I changed the oil with only 1000 miles since last change due to running it harder than usual.
I installed new plugs, air filter, (oil change and filter), and rechecked Starter Valve Synch. The bike idles fine and has smooth throttle response.
Can anyone give some insight to what these conditions might be spelling? I'm getting the bike ready for the 16,000 mile valve clearance maintenance. Should I show the dealer all this? I still have a year on the extended warranty.
Thanks (somewhat worried
