'13 300 jetting and plug? S2 head/cylinder

[poelinca]

What needle are you using ?

Try a different premix oil, with a lower flash point (like a semi synthetic one). Use full synthetic only if you run the bike pinned most of the time. That should deal with the spooge/wet plug a little bit, but it will not fix the jetting issue.

For jetting/needle/spark plug, I'd recommend you go back to "standard" and take it from there (most of us around here run 175/40). The problem may very well be somewhere else.

If you are running so lean for me it means you are trying to cover up a different issue with the bike that's causing it to run rich. First thing that comes to mind regarding this is it's sucking gear oil thru the crankshaft seal ?? or the float height may need to be re-adjusted ?? Something definitely wrong tough.
