I have read so many articles where people have lots of problems from voltage regulators to front wheel vibrations. Does everyone have problems??
Most front wheel vibrations are the result of lack of maintenance. Keep the tires inflated properly to keep the tires from cupping. This bike has tapered wheel bearings, front and rear. The bearings must be lubricated at 10,000 miles and whenever new tires are installed. Don't take the bike to the car wash to wash it. You will blow the grease out of the wheel bearings with the high pressure.The bearings will then rust and pit, causing them to need replacement.
Nothing lasts forever, but most EVO voltage regulator problems start when the regulator comes partially unplugged from the stator at the engine case. When partially unplugged, the AC voltage from the stator will arc to the pins at the regulator connection, causing the pins to burn away. This can fry the regulator and cause the battery not to charge. Just regularly make sure the regulator stays plugged to the stator and you should have miles of troublefree riding.
I own a '91 bagger I bought new. I've only replaced 2 regulators on this bike, and both were because they came partially unplugged from the stator.

Hi,
To check if you got a charging fault, get a multimeter and switch to voltage put across the battery. You should be getting at least 13.4 volts.
Turn lights on and this should fluctuate upwards. If your getting anything lower then what I stated you have a charging problem. Rectifiers and regulators can only really be tested of the bike with a specific tester. Hope this helps, let me know how you get on.

There is oil in the primary case and that's the same place that the alternator is located. It too runs in an oil bath. Not that it needs oil for the alternator to run, just that this place is a good place to put the alternator. The plug is made up of synthetic rubber moulded around the two wires from the stator. Over the years, heat and oil exposure have deteriorated the rubber in the plug and it doesn't fit as tightly as it used to. The only way to stop the oil leak reliably is to replace the stator with a new one with a new plug. I always put some RTV sealant on the new plug as well. The oil leakage won't hurt anything other than make a mess. The alternator will still continue to work until something else goes wrong with it. If the leak is bad, keep a check on your primary oil level until such time as you replace the stator.
Good Luck
Steve
