Spark plug reading

[BlasterIan]

Ok, after hours of tuning and opening the carb trying new jets, I finally got the reading I wanted!

Would you guys be happy with this plug reading?

This is with the following...
- FMF Fatty and Power Core 2 pipe
- Stock Carb
- 290 main jet
- 32.5 pilot (I assume its stock)
- Airbox lid made big holes in with a breathable water resistant cover
- air fuel mix screw at 1+3/4 turns out
- Spark plug NGK BR8EG

Cant really see, cut the threads off and post pic again. What I see looks fine but you need to read the colour of the ring.

Was this test done as per plug chop specs?

Next trip Ill chop off the thread, the MX store here only had one left of this plug. Ill buy another one then chop this one after a test.

i think it looks pretty good and those jet sizes are what i had with my fmf...

that looks about on cue if you ask me. i would personally like it a little darker just to be safe

If you are going to re test, do it with a new plug or you will get a false reading.
