I have an 09 1125cr. I did my first oil change on it. The manual say 2.7 u.s quarts. . I did that and the oil level on the dipstick reads about 2 inches over the full mark.. If I put in the amount to the full mark, It would be about 1.4 quarts. I know that's not enough oil to run that motor on... what gives ?
 
The manual was wrong that year. Along with a few other Harley manuals. Like sportster and V-rod specs.
 
Not pertaining to this thread in particular, but in general ... I think maybe these oil measurement threads are getting kind of overly obsessive at times ...... And I mean people sometimes really will go over the top to try and get the level EXACT to the point of borderline insanity ... Remember your bike won't explode if you're not DEAD ON the full mark on the dipstick ... whether it's on the kickstand or not .... your bike's motor has a lot more oil than it technically "NEEDS" to run ... Dipsticks give a range for an oil level because it's a flexible limit ... It's even MORE flexible on a dry sump motor like the XB's ... it doesn't care if you have 55 gallons of oil in the oil tank or 0.5 quarts ... as long as the oil pump doesn't run dry and lose pressure you're good ... wet sump motors are a little more sensitive to high oil levels because of foaming issues when the crankshaft stirs it up and sloshes it everywhere ... (but that would be something you'd see on a grossly overfilled motor) ... and since oil pumps cannot pump foamy oil this would be no bueno ...

Don't get me wrong, I'm not trying to say it's ok to put like a cup of oil in a motor and run it ... nor I'm I saying it's ok to keep pouring it in till it overflows out of the fill hole and run it ... What I'm saying is make sure you can see the level of the oil in the bike on the dipstick and if the bike is starting to get towards the lower limit of the dipsticks measurement markings ... That's the purpose of the FULL range on the dipsticks instead of just a narrow line you have to adhere to ...

Your bike actually requires a much smaller amount of oil to be able to circulate it through the engine and run without seizing up than it's made to hold ... but they call for much more than they "need" because these motors contaminate/wear down/dilute oil so quickly from high revs, transmission shearing, and other factors ... (it takes longer to wear down 2.7 quarts than it does to wear down 0.5 quarts) .... so they dictate the oil levels to try and make sure you don't wear out all of the oil in the engine/oil tank between the recommended mileage between oil changes ...

Don't sweat this kinda stuff peeps ... it'll drive you insane ...

Pertaining to this thread: that's a pretty decent discrepancy from 2.7 quarts stated in the manual to the 1.4 quarts it takes to put it to the full mark ... [confused]
 
I concur with the discrepancy issue. Changed my oil last night put 2.4 quarts in and I am about an inch over the full mark. No I did not run the bike(have plugs out..can't find my gapper), the bike has been on the stands. Waited well over the 4hrs stated in the manual for the cold check and it's still over the full mark. I put the Stahlbus oil drain plugs in so draining the excess will be easier, but not sure why it's showing overfull.
 
3 quarts, every time on my 1125. Sure, it was an 08, but it's the same motor. That oil change was drop the filter, oil screen on the right side and drain plug. Put 3 quarts of Amsoil 20w50 in it and go. My 1190rx says 3.3 quarts, it took 3.7 to actually fill it and get it in the middle of the sight glass range. Worst case, you get a little bit of oil in the airbox.

Both the 1125 and the 1190 must be checked on flat ground and on the sidestand, NOT upright on a lift.
 
I maybe able to help.. with my 09 1125cr I had to check it on upright while at running temp..(per manual and per local dealer specs). After yhr motor had a catastrophic melt down and I ended up with a 2010 motor directly from ebr it is different now.. there is no dipstick. There is a bung where the dipstick should be but it is just the fill port now.. the 10 motors have a sight glass and is to be checked via threw that. While at operating temp and on its side stand.(per local dealership who did the motor swap and also ebr). I contacted them in disbelief of what the dealer told me. Also I know that I have to open the fill cap or dipstick to let the engine depresurize and then the fluid level will drop to normal conditions.. just food for thought
