Sealing airbox leak - xj650rj

So after hunting for my air leak for some time, I finally found the culprit, it atlas of them 1. (after resolution, I will continue to test to ensure there are no other leaks) My airbox lid does not have a perfect seal all the way around. specifically in the front 2 corners. I've tried re-seating it multiple times and this is the best I can get. So with this in mind, i'm looking for suggestions for a resolution. Thinking of the following options:
1. Using a "soft" sealant to create a "gasket" around the gap. I need this to be not a permanent bond so when I need to get into the airbag in the future (chasing air filter) I can easily do this. I was thinking something like RTV sealant, as this can be cut with a utility knife
2. So sort of weather stripping material to create a "gasket" around the surface.
3. ordering a new lid

I've attached some videos for reference too. any other suggestions are greatly appreciated. Once I resolve this issue the bike will pretty much be done and able to be ridden.

 

The lid itself does not need to have a perfect seal; it's main function is to hold the air filter in place well enough that the filter seals against the fromt of the airbox, and keep out rain (and reduce intake noise, and take advantage of airflow pulses to help with intake efficiency, and...).
Spraying carb cleaner into the airbox (through any opening) will cause the idle to increase. That is not indicative of a vacuum leak.

Your vacuum leak lies elsewhere.

Please link the thread where we've already tried to solve this problem for you, so we can revisit the work that was done, and find the actual cause.

 

K moe is spot on, leak somewhere else or tuning is off.
