 +**Noises** \\
 +A common occurrence with Sportsters is all the noise they make. Especially for new owners, it's difficult to nail down if the noises are a sign of problems or if they are just normal. A list of noises that you may hear has been compiled to help with diagnosis or some just to ease your mind. \\

 +**The Dreaded Clutch Basket Wobble (L84-90 models)**. \\
 +This is a known issue beginning either from a worn out basket or trap door bearing or possibly a worn inner basket spline or maybe a combination of them: \\
 +The late 84-90 sportster has the stator mounted behind the clutch shell, the problem is the stator needs a tight 0.060 clearance to operate right. \\
 +A clutch shell wobbles even when the bearing in the trap door is good, but once it gets worn, it's enough for the magnets to start contacting the stator. Then it's catastrophic for the charging system. \\

 +**04-05 Oil Cap popping up**. \\
 +If you've noticed your oil cap mysteriously popping up, it could be a broken internal sleeve. One of the first symptoms is that the cap will not stay flush, but will protrude maybe an eighth of an inch above the tank surface. Eventually it will not click down in place at all. There is a fix for this instead of buying a new one. \\

 **Loose Battery Cables**\\ **Loose Battery Cables**\\
 Whenever you have electrical issues, the first thing to do is check the battery cables and do the basic four voltage tests. Then check the various ground points & straps. A huge number of issues are caused by battery cable deterioration and/or loose connectors. The negative cable to the frame is especially critical. All Sportster models occasionally have trouble with the battery cables but it seems to be even more prevalent on the rubber-mounted engine models from 2004-up (since the motor moves more in relation to the frame).\\ Whenever you have electrical issues, the first thing to do is check the battery cables and do the basic four voltage tests.

These OEM modules had a high failure rate, apparently due to the high heat in their mounting location. The MoCo stopped providing replacement units as soon as they were allowed. The only current choice for replacement is aftermarket versions (such as the Ultima brand).\\
