I have been trying to dial my mods in and everythig i do im rich at 145r/142/f im black I have my neddles at the third grove bad bog at quarter throtle I really get no response from pilot jets I put stock jets back in I feel i should be lean now but all signs point to being rich is the sticky choke / week springs giving me the probles here or what? thanks steve

 

my buddy has an 02 prarie stock and when he turned LEFT it would engage the choke keep it on and make the bike run crappy
this also happened on my cousins kfx 400
and is happening now on my vforce
dirt gets in cable and makes it stick
drove me NUTS

check to see

 

Happened to me too, right when I was trying to jet my quad too. It seemed to work good after a few more rides.
