So I'm using the factory specified spark plugs at the moment and im gonna go get some new ones, should I still get the JR9C plugs or get a JR8C that runs a little hotter? The bike still afterfires so we're gonna try replacing the plugs to see if it fixes anything. Here is a pic of what the current plugs look like.

I have idle problems with my bike, if I drop the idle below 2k it'll idle at like 1.5k then drop down to 1k after like 10secs, and it'll drop again after that.

This is a classic symptom of too lean at idle. Increase the a/f screws by 1/4 or 1/2 turns.
