I have a 2000 Mach I w/ v-force 3's and dp trail pipes. The sled keeps loading up at cold start-up. I'm not too keen on all of the adjustment available. I'm running the stock jetting on the main and pilot per dyno port due to having vf3's. Can anyone help. Just looking for ideas to try. Once the sled is warmed up everything seems fine.

try turning out the air screw 1/4-1/2 turn

by loading up do you mean it's fouling plugs? or do you mean it just real boggy when you try to take off?? Alot of sleds won't even move until they are warmed up properly, once they are warm they are ready to rip.. If you are fouling plugs, then try opening the air adjustment screw 1/4 turn, but don't get too carried away, check your plugs after doing that and see how its running. Also is it hard to start? Maybe check your needle and seats. good luck.
