My bike is a 07 deuce. My problem is that im burning/losing atleast 1 quart of oil in 3000 miles, atleast. My bike is spotless, other than I have noticed a few oil drops on my headers. Doesnt smoke a bit, and runs just as hard as every other 96in ive ever rode. Is there a common hard to find leak that happens while riding? My garage floor is spotless...

 

Are you over filling the engine and oil is squirting out the air cleaner? Feed or return line loose? Vent hose obstructed? Leaky valve guide seals?

Start the bike up from dead cold in the dark after it has sat for at least 12 hours and shine a flashlight on the exhaust at start-up. If you have initial blue smoke which stops in a minute or two chances are you have leaking valve guide seals.

 

Possible sumping problem.

 

next time you drain the primary fluid ,,,, measure it.....if its more than you put in , could be a bad seal on the crank

 

Thanks guys, I will see what I can figure out.
