I just got my 3.0 jet kit and uni pods in the mail. They will be on shortly. But I'm a newbee and need a lil help on setting them. There also seems to be a shortage of hawkers in the saint louis area to help me out. So any help would be greatly appreciated. Especially if there is pics involved. Thanks again, Paul.

Het Doc, if you post pics of step by step of changing the jets that would be great. You could even post it in the "sticky" section. Even use a screw driver or something to point out which jets are primary and stuff, I don't know about everyone else but that would help me out alot. I am kinda lame when it comes to "figuring it out"-NEVER LET YOUR FEARS STAND IN THE WAY OF YOUR DREAMS-

Does this help.
From www.hawkgt.com FAQ
The Hawk GT responds well to jetting changes. Since the bike comes from the factory set-up pretty lean (for emissions purposes) the main goal in rejetting is usually to richen things up. Altering intake (airbox/filters) or exhaust will usually require that you richen up the carbs as well.
When adjusting your carbs you need to pay attention to the throttle positions that you'd like to adjust. The following table shows the
approximate throttle range affected by the different carb components:
* idle to 1/4 throttle - pilot jets
* 1/4 throttle to 3/4 throttle - needles
* 3/4 throttle to WFO - main jets
Jetting is affected by altitude. At higher elevations the air is thinner and therefore the bike will run richer. The factory manual recommends adjusting the pilot jets to compensate for altitude (while the main area affected by the pilot jets is idle to 1/4 throttle it has some affect on the entire throttle range). Turning the pilot screw clockwise will lean things up. [Thx Kirk Roy]
Factory Pro has an excellent procedure on CV carb tuning available at http://www.factorypro.com/tech/carbtun.html. Stock, the Hawk came jetted with 132 rear and 138 front. It is believed this disparity in jet size between front and rear is due also to emissions control. Many listers have had success with using the same size front & rear jets, and most of the aftermarket jet kits also use the same size jet for front & rear.

Hey Doc, would it be possible to get you to take a picture of one of your mainjets (assuming they are Kehien jets)
Or just tell me if they are the round ones or the hex ones. And is there an extension that they screw into or do they screw directly into the carb body?
And does anybody know if the numbers on FACTORY brand jets correspond with Kehein jets?
The reason for all the questions is this: I took the bowls off my carbs and found that the jet sizes are 128 and 132. They are FACTORY brand jets. I am going to try changing the jetting around but do not want to buy a whole jet kit when I can go to the bike shop and buy individual jets for a couple bucks. Anyway, I have installed DYNOJET kits on a couple fourwheelers and they came with jet extensons. So I need to know if the extensions in my carbs are stock, or if they came with the FACTORY jet kit (that I DID NOT get with my bike).
Any help would be appreciated.Comment
