Kind of weird... I decided to change all the fluids in my scooter the other day. I had a shop do this last time. All went well, no problems encountered. When I filled the primary, I used 36 oz. per manual. When I drained the catch pan into bottle to dispose the used fluid, only 28 oz. came out. I guess an oz. or so may have been left in catch pan, but that's a 8 oz. difference. Weird huh?? I guess it's like most people say on here, do it yourself to be sure. Seems like the primary has a little less noise now. Just sayin...

 

most touring series primaries will hold about 44 oz of fluid.

on a simple change about 38 oz of that will drain and the rest will be held in the clutch basket and clutch plates.
more can be drained if the rider zip ties the clutch to separate the plates and let's it sit on the jiffy overnight- I will also start the motor to spin fluid out of the clutch.

as the clutch plates absorb and hold fluid, it is important to use compatible fluids on each change- same brand fluids are always compatible. changing brands can lead to slipping and engagement problems.


ALL fluid capacities on your bike are meant to be checked visually- the method varies by model year and is in your owners manual.
Check your manual again for capacities and method to check level- the 36 oz you quote above seems low

That's some good info right there.
Thanks Mike.

 

According to the service manuals I use it says 38 OZ for change and 44oz if cleaned.
I do mine by eye sight through the derby cover.

 

I just drain it, pour in a fresh quart, and button it up. Have done it that way for years with no issues.

 

"Zackley" 32oz put the cover on, ride. I have done this on 3 Harleys since 2005. No compensator issues or finding neutral issues, less clunk into gear.
