I need some help in figuring out where to head in jetting on this bike. Due to recent weather changes the bike seems suddenly lean. The tip of my muffler went from alittle dark like it was alittle too rich and now its gotten alittle bit of whiteness to it. It really hesitates off the bottom, when rolling on the throttle real slowly it doesn't but say you crack it like you would normally and it gags like bogs almost to the bike sometimes it seems like its gonna stall. Then cleans out and rev's freely the rest of the time unless I chop the throttle fully and try it again. The other thing it does is when I chop the throttle it pops some when it idles down.
I'm thinking it is cause its alittle lean cause when its dead cold now its become such a pain to start. Once I get the first warm up the day it usually starts 1-2 kicks. It currently has #40 pilot and the needle is #4 clip and the main is a 178. I have tried turning up the idle but that didn't do anything. I was going to lower the needle to clip #5 or would I be better off just going up on the pilot one or would going up on the main one to #180 work? I know jetting is all trail and error but I just need some input on the direction I should go since my 4 stroke jetting experience is very limited. I'd like to get it dailed in better before the race this weekend. Last weekend a rider went down in front of me and I stalled the bike going from 3rd to dead last. I couldn't get the bike restarted and I didn't lay it over. I was two laps down before I finally got it restarted and I think its become harder to start cause jetting is now off. The temps are in the upper 30's to 50's and I'm running trick 110.
