And what power valve spring and turns in?
erik,
stock jetting, bike has 2hrs on it, checked it all 4 times I rode it plug looks pretty good. all been in 32-40* F temps so not as rich as it will be during the spring. also to my understanding and the manual/videos the PV adjustments do not make any changes at all to anything above the midrange into the top end/over rev. the PV positioning is untouched from factory

The Jetting thread
Unfortunately I ran the bike out of gas so looking at the plug after multiple 4rth gear pulls in the front yard was botched by it bogging and trying to get it to get it halfway up my 1000ft super steep driveway.
That said plug was darker and blacker around the ceramic
Will not be able to test Saturday due to rain. I believe I am going to twist the PV adjuster all the way out as a test
*edit, I suppose I should try the jetting first before making the mech SoCal change of PV adjustment to keep it one thing st a time
