I brought my 04 grizz into the shop to get the k/n air filter and dyno jet kit put on. I put on my HMF at my home. Well, the dyno instructions says to put a dj155 on if ur below 3000 ft and you have an airfilter and an aftermarket baffle. So i go to pick up the grizz today. While riding it off the trailer, I tried to give it some throttle to feel the power. When i tried to give it throttle, it hesistates. The rev is high but theres no speed really..the last thing i want to hear is that the dealer f***** up!
HELP PLEASE

 

if i read it right, you had the dealership dial it in before you added the pipe? sounds to me to be running rich. the hesitation on throttle up is due to the idle screw. turn it out to 3 1/4 turns.
