This may sound odd,but your charging system is working.Excessive current not needed by the bike is dissipated by heat in the regulator module.Just so happens,it's mounted inside the left side of the shelter.
When running right,that thing has to dissipate around 100 watts.I will get quite warm.

This is another great example of why this forum is so valuable. It is good that he noticed the excess heat on the left side; even better that you told him it is normal - nothing to worry about.

Thanks for the info I was hoping for :) I thought it would be normal to get hot just that during my last 734 mile non-stop ride other the a few minuets for gas etc. I really noticed the heat even with the air temp in the 96 degree area I thought it was extra hot and was wondering if I was going to have to do a poor-boy job on it soon. ( I will be but hope when it get cold out as a winter project)
If I was to turn on some of my extra lights during the day would this help it run cooler being it would be using the current instead of just turning it to heat?

I agree that the heat is coming from the regulator but I would add to check the connector with 3 large yellow wires through it under the left side cover (in front of the battery). If this connector is corroded or shows signs of being hot (such as discolored or melted) then this could cause the regulator to run hotter than normal. With corrosion in the connector, the regulator is fooled into thinking the stator isn't putting out enough power and calls for more to overcome the resistance of the corrosion. It is an accepted procedure to remove that connector and solder the wires to cure the problems associated with the bad connection. If your bike has not had this done then I would recommend doing it. This connector is probably the single most common reason for stator failure.

I may have some details or terminology wrong but these are facts. Corrosion bad. Soldered wires good.

I agree that removing all the plugs related to the charging system and soldering them provides the best connection possible.Here in Louisiana,it's almost necessary.

Agree the regulator is where the heat is coming from. Also soldering the wires is the way to go. The stator actually puts out its maximum voltage all the time. The regulator shunts the excess voltage off to ground thru the two green wires coming out of the regulator. Soldering them too isnt a bad idea

When it come to that stator or regulator hardwire and soder everything you can . It's cheap insurance . Don't ask me how I know
