This kit is all you need to remove the oxygen sensor and plug the exhaust pipe. It takes the bike out of "closed loop". This richens up the fuel .5 to 1 full point from idle to 6200 rpm.
It DOES NOT add any fuel above 6200. If you are just using this with an open end cap and intake, your bike will still be way to lean above 6200 rpm.
You would need to use our piggyback fuel programmer at that point, to keep yourself from running to lean
THIS KIT ONLY APPLYS TO USA AND CANADA BIKES.
