I recently installed a small M4 street slayer exhaust from a gsxr600 onto my '00 SV650. The bike seems to be running fine, but I figured I would check my spark plugs just to see if it's running a bit rich or lean after doing the swap. I'm assuming the exhaust flow is a bit worse since the exhaust isn't made for my bike, and the muffler has a slightly smaller inlet diameter than the old one.
So I pulled the rear plug, and it looks like this:
I'm guessing it's a bit rich, due to the colour of the base ring, but this is the first time I've done this. Also, I pulled the plug after the bike had cooled down from a previous ride, and the bike was shut off from idle. I'd like to eventually de-snorkle my air intake, and do a proper carb tune, but for now does this look pretty normal?
