I just bought 04 Baja 650 X. Its plenty fast enough for me stock. But I would like to modify the end cap on the exhaust to make the bike sound a little meaner. I guess all I would have to do is install 1 jet right? Or can I do this mod with out any changes? Thanks, D

 

Right from factory my ds650 baja x was running rich so we moved the clip and it ran fine after that i installed a uni air filer and modified my endcap without any more changes to jetting so you should be fine to run it without jetting.

 

What do you mean by the clip?

 

the needle clip inside the carb you can move a little clip on it to make it richer or leaner without changing the jets

 

I hate to bother you but is it possible you could give me a little detail on how to do it.

 

To do this, you are going to have to take the top of the carb apart as follows:

1) There are three screws that hold on a brass colored metal cover over the top of the carb. The screws are Phillips head, but soft and loc-tited on. So, as soon as you try to take them off with a screwdriver, they will strip. I used some small, needle nose visegrips to get them off. After you remove them, you will want to take them to Home Depot (for a size reference) and get allen headed screws of the same size to replace them and make things easier in the future.

2) After you take the carb cover off, you will see a big spring, pull it out. Then, you will see be a black rubber diaphragm looking thing. Down in the middle of the rubber thing, you will see a light gray plastic tab. Pull on this tab GENTLY to remove the needle. The needle has several tiny washers, spacers, and springs attached to it, so pull it out CAREFULLY to avoid losing anything.

3) At this point, I made a little drawing of all of the pieces that attach onto the needle, so I wouldn't forget how they went back together. Now, take all of the spacers/washers off the needle. Be especially careful with the little tiny spring, since it has a tendency to fly across the garage and get lost. In fact, you may want to order and have another one on hand in case you lose it.

4) You will be left with a tiny "c clip" that notches into one of five slots on the top (rounded) end of the needle. Move the "c clip" one notch down (towards the sharp end of the needle) to make it richer, or lean it out by moving the "c clip" into the notches towards the top (rounded end) of the needle.

5) After you adjust the position of the "c clip" put all of the washers and spacers back on the needle the way you found it. Then (I used needle nose pliers to do this) put the needle CAREFULLY back into the hole in the center of the rubber diaphragm. You will feel it sort of "snap" into place.

6) Put the big spring back in, and then put the cover back on the carb, being careful to line the rubber diaphragm up correctly (there is a little round piece on the diaphragm which lines up with a round notch on the top of the carb-it will be obvious when you see it).

7) Screw in your new allen bolts and you should be good to go.

 

Hey Jusrlax. You could not have said it better. Thank you, D
