You also need to remove both main jets. The main has the emulsion tube (called 'holder' in the left picture) behind it, with the jet needle (also called 'collar') behind that. Be sure you get these little parts out (part #16017 on the diagram), as they could fall out on their own if you don't. When you replace them, check in the carb intake to make sure they're poking through. They only go in one way. The longer, narrower end goes in first.

Some notes on the main jet:

*You can reach the main jet more easily than the pilot, but they have the same sized screwdriver slot. This makes it a good candidate for figuring out what tool to use on the pilot.

*You need to hold the emulsion tube still with an 8mm wrench in order to get the jet out of it.

*Remove the emulsion tube and look through the holes in the sides against sunlight to make sure they are clean. Clean the same as the pilot jets (see below).

*When reinstalling the emulsion tube, not all the threads will be hidden in the carb body. That is normal; do not over-tighten.

====Cleaning====

The first thing you should do is look through those pilot jets that you removed. Make sure you can see that the very small hole isn't plugged up. Spray it out with carb cleaner, then pull a single strand of '''COPPER''' wire from a piece of 14-18 gauge that you probably have laying around someplace, feed it through the pilot jet hole, and roll the jet around the wire.

Once you have carb cleaner coming out of all the proper places, set the mixture screws to 2 1/2 turns and reinstall the pilot jets, which should also be clear.

Once you have carb cleaner coming out of all the proper places, set the mixture screws to 2 1/2 turns and reinstall the pilot and main jets, which should also be clear.

Now [[How do I remove the carbs to work on them?|reinstall the carbs]] onto the engine, and make sure the carbs are FULLY seated into the intake boots on the engine. If they aren't properly seated, the bike won't run properly.

If you have trouble figuring out where everything goes when it's time to put it back together, see [[Carburetor photos]].
