Decided to start the stage one add ons myself. I decided to start with rejetting the carb, get the hard part out of the way first. I have never worked on carbs before, figured it can't be to bad with the manual. Everything is disconnected but the one little cheap @#$ screw rounded out. So right now it is hanging by the bracket for the throttle cables by one screw. I have tried everything I can think of including a screw extractor that won't get started due to the lack of room to beat it. I have read some outstanding ideas in thiss forum so I am trying to pick everyones brains. Also, once it comes out which jets am I replacing? the main jet and needle jet or the slow jet and main jet? Should've researched this one a little more. Any and all ideas are needed.

 

As far as getting the screw out, a Dremel with a flex shaft and a cut off wheel will make a nice strait slot in the screw to grab with a flat screw driver, or just cut thru the head and that should leave you enough thread to grab with pliers ahfter the carb is off.

As far as the jetting goes, your going to need to change everything at once. If you jet up now with a stock air filter and stock pipes your going to flood the thing out.

Some people like em, some people don't, but I used a Yost Power Tube on my last carbed bike, and like the results. They can help set up your bike to your area, pipes, altitude, etc.... I even think you can call them, tell them them application, and they will send you the tube and jets together.

 

Done the same thing on one that I was doing. I was able to get a pair of small, narrow vise grips on the head of the screw and get it out.

As far as jet size goes, I would go up 1 size on the slow jet (Needle), and 1 size on the main jet. I would also cut off 2 coils on the slide return spring, and install a 1988 1200 Sportster needle. The 1988 1200 Sportster did not have an accelarator pump, so that needle has a different taper, and you will get better response.

You also need to remove the cover on the idle screw and adjust you idle. To remove the plug, carefully drill the little plug with a small drill, just enough to get a wood screw started. Screw a wood screw in just enough to get a hold, and pull on the screw. The plug will pop right out. Adjust the idle screw out about 2 turns from full in for starters, then fine adjust your idle to where you want it.
