Those must be rear panels, taillight and rear fender from a PAL (JDM) af17 scooter! Nice job! :2thumbs:

hello everyone! i am thankfully back to working on the engine swap project after a long wait. i have successfully mounted the engine and changed the shock mount with an extension to get proper ride hight. i have hopefully the right carb on the way so the final thing to do is wiring. from what ive seen the wiring might not be as straightforward as i thought, and i may need to get a new cdi and wire that in separately... if anyone has had any experience wiring a af18e engine to a honda elite e af05e frame and could help me out that would be awesome! will also be posting some photos soon if i can figure it out on my computer. thanks again everyone!

anyone know if i can just keep my old cdi from my sb50p? google is telling me the sb50p and the af18 cdis are powerd differently and i will need to get a new 4 pin dc cdi and rewire that into the harness and then tap into break light power line so it has power if engine isn't running?. doesn't seem too hard but i would rather use the nice cdi i bought and i haven't seen anybody else having to deal with this so want to make sure its actually necessary
