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!

The lack of torque or pulling power is a lean condition. If its a 38mm ASII, and its hot, humid and a bit of elevation JD recommends 40 JDRed#4 180. I could see people running around clip#3 and 175 main maybe.
FWW I think there was a typo on JDs sheet (
http://www.gasgasrider.org/forum/sho...4&postcount=24 - second attachment) says to start with a 180 but then drops straight down to 168 for altitude. I think it should read, 178, 172,168 respectively.
Move the needle back to clip #3 and drop in a larger main and then see if it'll pull up a hill any better. Do you find the engine racing or running hot as well after a run on the main jet?
