2003 Honda CBR 600 RR bypass ignition switch

SOURCE: fuel petcock

The petcock is what the fuel flows through when it comes out of the gas tank. It probably includes: * A switch with positions for On, Off and Reserve. * A fuel line going to the carburetors. * A vacuum hose attachment which attaches to a carburetor which tugs on a rubber diaphram to let gas flow through. * An overflow/drip valve from the vacuum area. It's located right under the tank on the rear/left side.

I had an 07, I had to remove the lower and side fairings and then the bolts are visible, dont just lift it up because wires and the fuel line will be connected and tight. When you lift it, lift easily so you dont just rip everything, you should be able to lift it high enough to disconect the wires without damage.

SOURCE: How do you remove the ignition switch from 1999 Honda CG125

Usually large cir-clip or nuts an bolts, why don't you get one from a breakers? anyhow there's a bit off stuff to come off it before you'll see what your doing, make sure its possible to remove it with or without steering lock on or off. The barrel can usually be separated from the switch but be careful not to take summit apart that wont go back again. A clever engineer would be able to use an old CG125 key and make your barrel fit that key! But alas i'm not blessed with a good locksmiths skills. Good luck - the Yeti
