holes in the air box

[pinner]

I have recently reinstalled the factory airbox on my 83 1100E. The jets that are currently on the bike are 125's. The original owner of the air box drilled holes in it for better air flow. I need to find the corect size jets for it but don't know where to start with sizes and don't really want to buy a bunch of sizes i don't need. There is a lot of holes maybe the diameter of a pen. Should I start with 2 sizes larger or just stock?

or put some tape on the interior/ exterior of the box to cover holes...

Stock jets on your bike are
main jet 110
pilot jet 45

Someone already raised your mains. How do your spark plugs look? Are they dark (rich) or clean (lean)

So the previous owner didn't think removing the HUGE lid on the top of the airbox was enough to enhance flow on a STREET DRIVEN motorcycle? Too bad, another sad story of a hacked up stock airbox. Does your bike have the OEM paper canister filter, and do you have an aftermarket pipe?
