jetting help

[BryanMcc]

trying to get me jetting dialed in...in the bike now (2010 ec300) is jd needle, clip pos 2 from the top, 170 main, 42 pilot. Im currently waiting for a gasket to adjust the preload on the PV assembly because it rattles and i will clean in while im in there because i believe it is sticking after long fast close to wide open sections (zero bottom end, trouble getting on the pipe, i shut the bike off and it usually runs fine so i believe its sticking open). So when the PV isnt being sticky the bike is clean on the bottom, and midrange, but uphill or with a load (like deep sand) it has a hard time clearing out. Downhill light load the bike runs amazing, zero hesitation, very crisp. I think i still may be a little rich but there is zero spooge and if i was rich would the high load sections require a little more fuel and run better? plug is kind of black and has never fouled although i have changed it just to rule that out. Thanks for the help!
