my brother in law has a 1992 1200 sportster he had the oil changed at a dealer and it was way overfilled and started dripping oil out of the lil filter above the carb,took it back to the dealer they changed the oil again cleaned the bike up but now its still dripping outta that little filter when you overfill your oil does it damage something that would make it continue to leak oil?

 

Keep it a bit below the halfway mark on the stick. You can use a turkey baster to get the excess oil out if needed.

 

+1 with freebird but remember if a filter has gotten saturated with oil it will take some time to blow out all the excess oil, tell him to take her out on the freeway and run at high speed for a bit then clean it up and he should be good to go.

 

agree... and he should wear some old jeans that he does not care about - pretty likely to get the right leg oil splatted... while blowing out the excess.
the key was mentioned above = dont fill the oil in a sporty over half way or so. i usually keep mine about 1/4 on the dipstick.

 

we have taken it out on the freeway for about 10 miles going 70+ and it keeps dripping,could it have damaged anything?

 

If its blow by then no you haven't damaged anything. Whats the level on the stick read?

 

its just touching the dipstick maybe by a quarter inch to a half inch up it

 

The breather bolts may need new seals and or the umbrella valves in the valve covers are bad.

 

Remove the ac cover and clean it.
Examine the air filter. If it is full of oil, either clean it or replace it.

If the filter & housing are full of oil, it's going to keep leaking/ dripping until you clean it.

 

Also, especially with the EVO based Harley engines, stay away from the crappy 10 micron (or worse yet the newer 5 micron filters) that they will try to insist on using.

Go with either the 'long' or 'short' 30 micron filter which was designed to be used on the EVO's. I run these on all my Harley's, even the TC models.
