Primary fluid level

Primary fluid level
Changing out all 3 fluids on my scoot. Followed the manual to a tee. Filled tranny with 20oz and it reads over the full mark. No big deal. I'll just drain some out. My question is the manual says to add 32oz to the primary. Don't want to overfill this so how do I check the level on the primary. No time to search this as I'm in a hurry. Thanks for the feedback guys.

easier:
bike on jiffy stand.
pour in lube until about 7/16"~1/2" from bottom of the clutch inspection hole in the primary.
put cover on and ride.
the primary lube spec is not crucial, the lube is for the chain and tensioner and for the clutch plates and discs. it is never pumped or under pressure, it just splashes around inside the primary case
the reason that HD gives no definative OZ spec is that the amount of fluid held by the clutch is unnown unless the assembly has been dismantled, cleaned and reassembled ( Dry).
Most of us just drain the fluid, work the clutch a few times to get some of the goop from between the plates and discs, put in the plug and pour ( wet).
you do not want to have so much fluid that the cover is "underwater" if the bike is on it's stand- it'll leak and be messy

I fill mine to the point that the chain sitting on top of the tensioner is submerged in oil so it follows that the tensioner is submerged as well. Primary has been much quieter since using this method.
I swapped out my compensator for an SE compensator at about 9k miles and my tensioner was already showing some nice grooves cut in it so I swapped it out too and started filling to the level stated above.

Yup. what he said. As long as it just barely touches the bottom of the clutch basket it will sling oil everywhere inside the primary, which is what you want. If you get too much oil in there it will actually make shifting a little bit harder because the spinning clutch pack has to "plow" all that excess oil.
