Oil on plug. !?

[soulboy74]

Now I have been noticed that each time I pulled the plug there's oils on the plug a bit just some on the threads and a bit on the crown part! Is this normal !! For 2 stroke engine just been out again for a few miles today and doing plug chop ! It's looking a little bit lean this time slite Gray to the electrode ! Think I might have to richer it up a little bit to get back to brown ish should I just lossen the air mixture a tad more and check it out ?? Best foot forward soulboy74 ✊

After a few goes with plugs the crush washers fail and allow some oil to pass, what you see on threads.

Usually oil on the electrode is a rich mixer.

A very well set up bike would be edge to the light brown

How are you doing you plug chops?

I do the folliwing :
Mark 1/4, 1/2 and 3/4 on the throttle position.
Warm bike up
Do a test run at position holding it there for around 1/2 mile
Pull clutch in and turn ignition off at same time
Keep clutch pulled in and coast to a halt
Check plug
If the bike is stock, i would set it as per manufacturer settings.

Set air screw at 2 screws out and 1/4 turn and see what affect. Wait about 10 seco ds to hear the motor change.
Screw out to richen the mix.
You shoukd come up with something between 1.5 and 2.25
