yea installing a jet is easy just make sure when you put the new one in to just snug it dont try to torque it down, cuz if that jet breaks and half is stuck in there that will suck, and adjusting the needle aint to bad either take your time take it apart move the clip, cuff your hand or hold it in a rag sometimes the clip will fly off when trying to get it off and can get lost easy and ruin your day, then just move it on one of the other slots there should be 5, at stock its in the middle slot you might not even have to mess with the needle but just saying if u do.
