| The "DynoJet" kits (and many equivalent ones) can be an issue. Typically, they replace the factory needle, emulsion tube, main jet & diaphragm/slide spring. They also recommend that you drill the slide vacuum hole out for quicker throttle response. The DynoJet emulsion tube and main jets are not compatible with the Keihin emulsion tube/jets - they use different threads. There are even FAKE Dynojet kits that have shown up on the market, presumably from China ((Fake DJ Kit - https://www.dynojet.com/warnings/PressReleaseKnockOffJetKits.pdf)) | The "DynoJet" kits (and many equivalent ones) can be an issue.

| - | While some people have had satisfactory results with the DJ kits, if you are having trouble getting a good tune on the carb, I would remove all DJ items and restore the carb to Keihin parts including buying another slide if it's been drilled. The stock parts are good quality and will provide excellent operation if the carb is tuned properly. | + | While some people have had satisfactory results with the DJ kits, if you are having trouble getting a good tune on the carb, remove all DJ items and restore the carb to Keihin parts including buying another slide if it's been drilled.

| From the factory, there is a cap over the Idle Mixture Screw. This needs to be removed to make IMS adjustments during tuning. It does not need to be replaced when done, but the cap is available as HD P/N 28015-01 if you would like to replace it when done making changes.((IMS Cap - http://xlforum.net/forums/showpost.php?p=595622&postcount=9)) | From the factory, there is a cap over the Idle Mixture Screw.
