That left plug looks pretty crusty almost looks like burned oil more than running rich.. Probably running a little rich from that 140 jet. If you're loosing the ears leave the 140 jet and change the 38 pilot jet to a 40. Degoating your ride sometimes may actually hurt the scavenging effect in your exhaust so your stock main jet probably didn't need to be moved up to a 140 (I know you didn't do it, previous owner). But with the earshave you will be pulling more air in and a 42 jet may be a bit too much, it was a hair to big on my bike after my earshave.
You may need a bit larger but I'd start with the 140/40 with 2 shims under the needle.
