yes sir , delete it all off the bike.
Usually for the “engine side” , we sell these blanks below:
EGR Valve Blanking Plate / AiS Delete Block Off Kit – Various Hyosung Carb Models
Then STEP 2 ===
Go to the airbox –> Make sure the airbox does NOT have open ports , block them. Those ports are what feeds those external emissions canisters on your bike.
Step 3 ===
See the “clutch arm” behind the rear engine ? –> There is a thick 10-15mm port , feed a hose there and make sure it goes to the airbox open port of the same diameter
This step 3 pipe is either overflow to airbox (which is what EFI bikes do anyway later on) or you can overflow it to the road (and block the airbox port) like below diagram
If you don’t have Hose #13 , you will find it most Hyosung Engines at your local dealer in your state or ask any major breaker in usa that has a Hyosung and quote the part number 13870H29B00 it is called “Crank Case Breather Pipe” and it has a “SLIT” at the bottom to stop road debris being sucked in to the crank! (very important)
