Airbox Gap

[darkminion_17]

There is suppose to be a gap all around the cover. The filter is sealed when the cover is tightened and presses against it.

There HAS to be a gap, how else is the air going to get through the filter and into the carb!!
Geesh,,,,

Thanks IHCubCadet147 and DarkMinion. I'll run the airbox with a gap until I hear otherwise.

This is self evident on the older round style filter. If there wasn't a gap, how else would air get in!

But with the quietline models, there's the black tube that connects the airbox to the engine flywheel fan. This means that pressurized air enters the airbox from the back plate. If there's a gap, air will actually be exiting the gap at all times - because the fan supplies more than the engine needs. If there's no gap, air will be forced down the carb, kind of like a weak supercharger.

I'm not trying to be difficult, I just wanna know how it's supposed to be setup per factory.

Here are pictures from my 1200.
Yes, the a box cover seals all the way around.
The filter measures about 1 5/8" thick but it's older so the rubber seal is somewhat smooshed.
The depth of the cover is also 1 5/8".
When the filter is set in the cover you can see the flat edge lain straight across.
If you cover is not sealing at the edge I would look at the depth of the divot (for lack of a better word) where the stud hole is. Maybe it got deepened somehow and does not let the cover go down on the stud far enough??
