2005 Boulevard oil leak (help identify)

Newbie to the forum and to the Boulevard. I noticed while moving today (battery charge / gas / etc) that there was a little oil under the bike. Is there a way to identify where the oils is coming from and are there any known oil leak issues with the boulevard? My first to do item is to check the oil plug and see if its coming from there and just needs to be tightened but any other help or pointers you can provide is much appreciated.

First, make sure the machine is upright, level and straight, then check the sight glass for proper oil level, on the right hand side.
Overfilling the motor & transmission with oil can cause oil leaks in several places.

As far as the oil plug leaking, if the plug bolt has been cross threaded or the sealing washer left off, either situation must be corrected.

Another area which frequently leaks, is the oil filter base.
The usual reason for that is someone left the previous oil filter gasket on the machine.
Of course, if the filter was forced on (cross threaded), that will cause a catastrophic motor oil leak.

What Psyco said, ... and since this is a 2005, how long did it sit before you purchased it?

I would recommend filling it to the proper oil level. Then ride it to get it hot. Bring it back and park it upright using a stand or some blocks. Check back in a couple of hours to see where the leak is dripping and trace it back to it's source.

If it's coming from a bolt, or plug, it should be easy to see where.

Likely places to look, ...
  1. Oil Plug - Check to make sure it's tight
  2. Oil filler cap - As Psyco stated, check for cross threading and the o-ring seal.
  3. Front Timing mark cover - Left side on the Stater cover on front. Make sure it's not cross threaded or loose.
  4. Crank Case bolt cover on the stater cover - Check for cross threading. There is no seal on this, just a tapered metal on metal seal.
  5. Crank Case Clutch cover - Check two things, ... a) the gasket - check for dried out area or broken, ... b) Check the bolts for any leak. If the clutch has been replaced, the bolts may not have been put back where they came out. They are different lengths and can cause issues when the long bolts are put back in the short holes

Ride your bike, your way, at your speed, for your reasons. Never let anyone else decide who, where, how and why you should ride.
Ride for the love of riding and nothing else and every trip will be an adventure and a memory to be relived over and over.
