surveyor is your 145, khien, dynojet, or did you just go to a dealer and ask for a 145 main jet and they gave you one. ive herd kehien jets are the best[img]i/expressions/face-icon-small-smile.gif[/img]

 

stock kehin jet, I also picked up a 148 in case I needed it..I have some shims as well, but did not need them..with stock exhaust
either dealer, sudco, or mike penland has them.(jets)
you can change them on the quad, no need to pull the carbs off & split the stack..
hope this helps..
