    Hey Snoop,

    You gotta pull the carbs to start, and tear them apart. If you are comfortable with this then.... you can ask the next step.

        You can use a 145 main jet in front and 138 in the back from my experience.

            Agreed. I was going to do it but I am by no means an expert. I vote it comes from JD or Gino.

                what about tuning after the pod installation, I was told I would need an exhaust gas analizer in order to get the mixture set right. Have any of you guys done this or did you just leave it alone?

                  That's going a bit far. If you feel like paying $100 an hour to dyno tune your bike for the extra half a horsepower, be my guest.

                  Then again, you could just put a 145 and 138 main jet in like I said.

                          Thanks for the info guys!

                          Like I said earlier I already have the Factory 3.0 installed, I just didn't know what I'd have to do as far as adjusting and tuning in the event that I put on some pods and hey presto the hawk starts running like shite. When I get the pods I'll try JD's settings listed on the milktree site.

                            The specs shown on Milktree's site have been dyno tested with an o2 sensor, plus road-tested "real world." They are definitely "ballpark" for Uni pod/full exhaust setups, at sea level to ~2000'. And, if you hot up the engine, the specs don't change much at all. Factory's recommendations included with the kits are fairly good, the only change I've made over the years is sticking with the original 42 pilot- seems to work better on most bikes, and gives a lot better fuel economy.

                              You HAVE to keep elevation in mind. With my pods and M4 i'm running 150's front and back, and could probably benefit from maybe going a bit leaner. Possibly 148 in the rear.

                              It would be cool if someone would take on buildng a Hawk-Jetting database that would include.

                              Airbox: Stock, Free-Flow, Modded-Free-Flow, Pods

                              Elevation: (in my case 4500 feet)

                              Anything else?

                              That way people could search for a bike with similar to their own and get a good starting point.
