i have a 2008 ultra....was changing the fluids today and removed a small allen screw...pointing straight down...on the right side in front of the engine oil and tranny oil drain plugs. only about 1/2 cup of "oil" fluid came out of it...does anybopdy know what this allen screw is for?

 

You say "small" but it sounds like you took out the plug where an oild cooler goes into. I think thats what it is for. Did it face forward on the bottom of your scoot?

 

Just went out and looked under my scoot and I see the plug you are referring too on the bottom of the actual part of the cases where the crank resides. Not sure what it is there for but thats not the oil drain plug.

 

that is the oil plug for the crank case. It is not intended to be removed. if you do a search on oil sumping this is the plug that gets removed to check to see how much oil is in the crankcase. Put it back but be carefull not to over tighten as you do not want to crack your case.

 

after i changed all the fluids, i gave it a test ride...everything seems to be ok. i am concerned that a small amount of oil came out...do i need to replace this oil and if so...how?

 

You definitely need to buy a service manual for that nice ride...it could save you big money in the long run.

 

you are good. if a lot of oil came out you would have problems.

 

thanks guys....i appreciate the help.

 

I believe (not positive!!) that the screw you removed is also the one you remove to put in an HD or other oil temperature guage.
I would change the oil or at a minimum, keep a close eye on your main oil level.

no wrong plug for that. why change oil he all ready said he changed the fluids? all he did was drain a few ounces of oil it will not effect anything.
