Below is the spark plug that I had been using. It's the one that came with my kit. I did purchase a BR6HS Plug awhile back, but hadn't put it in the bike yet. From your pictures, it looks like it could be too Cold, or too rich? Would this mean that I'm running too much oil in the mixture, or am I misunderstanding the cold/rich/lean/etc designations? Also, if I'm working on tuning the carb, how should I go about cleaning the plug so I know what kind of effect I'm having with my configurations?
