I just purchased a 2009 SE Ultra, one of the mods is the front wheel was changed to a 21". Hence the bike sits about 1 3/4 to 2 1/4 higher in the front then stock.

So I do my first oil change this weekend, motor/tranny & Primary. I put in the recommended levels
Motor start out with 3.5 quarters
Trans - 1 quart
Primary - 38 oz but could only get about 37 oz in before is started coming out the top

Checked the levels and they are all high. So that's when I realized that the front was higher and maybe causing the levels to appear high on the dip sticks and overflowing the primary a little when filling.

So anyone have any suggestions on what level I should run at because if the front is higher does it need the same amount of oil or less. If the same amount as a level bike then the dip stick will always show high.

Or maybe I should do my oil changes on a jack to level the bike.

This is my first Harley so any help would be appreciated, I love the bike, just want to make sure I'm doing the right thing.

Thank you

 

Has the front suspention been lowered to compensate for the 21" wheel?

Physics tells us that elevating the front and leaving the rear in the same location creates a bit of a triangle, i.e. the front is raised but the further you move to the rear the less effect raising the front has. And you oil tank is closer to the rear.

If you want check it level, roll the rear onto a 2x4. Should be pretty close.

 

Awesome, thank you very much

 

Filling your primary on the sidestand?

 

Your 21" wheel shouldn't be affecting levels that much. I always add 3qts then check engine oil and add from there to the desired mark. I run mine halfway on the dipstick and hardly ever get 3.5qts in it. My primary very seldom ever holds 38ozs. Especially on a quick oil change. Usually 1qt gets it right where it needs to be. Tranny always takes 1qt and is usually dead on the mark.

2010 Limited with some stuff

 

the book will show you exactly how full the case should be with the bike level on the wheels... I believe it is to the bottom of the clutch plates.. and I would put in enough to raise it to that mark..

 

I also put a 1" piece under the jiffy stand to counter act the extra lean.

 

Problem number 1.
