94RS
No fucks given.
Not a huge loss, but it's there.
The dip at 4500 can apparently be fixed by switching to the XB12 lid. (03-04 XB9 on left, 04-05 XB12 on right)
Supposedly the dimple helps to force air into the velocity stack faster. I guess it worked since Buell switched the design on all bikes to the dimpled version in '05.
From what I'm hearing, the low end loss can be recovered by opening up (cutting holes into) the lid.
Which I guess also worked since Buell added a few holes in '06, then even more in '07. This is an OEM '07 that I'm trying to find.
