Trying to build an RS which doesn't use a key or a starter so this is up for grabs now. It deletes the ignition barrell, however, the key still needs to be secured within the antenna ring. Looking for £40 including postage.
The right switchgear becomes the ignition. On/off switch and you also have the engine start button. Hopefully this helps. This is a general video which covers the majority of bikes. The guy mentions another wire is required for some models due to the immobiliser, however, not for the 1098 as the key will be located in the immobiliser ring. https://woodcraft-cfm.com/collectio...981198-keyswitch-elimination-harness-assembly
