I had the very same problem myself!!! The electrics on a motorbike are
very complex and its very very difficult to cut down the main wiring loom
- even if its at all possible!
The first motorbike engine I used for a kart - I messed up the
electronics. It was an RXS-100 yahama motorbike engine. In my
disconnecting of wires and attempted revivial - I blew the main EDU
(Electronics Diring Distribution Unit)/CDI (Capacitor Discharge Ignition).
course I didnt know what I had done - so I went to a local motorbike shop
- went out the back - and asked the mechanic a few questions -
specifically the wiring of the RXS-100. Fortunately - he knew the engine
quite well and he could tell me exactly how to wire up the engine -
removing the wiring loom from the equation, and as a result of his
instructions I narrowed down my electronics problem to the blown EDU. I
bought a new EDU - and my problems were fixed.
On my second motorbike engine - I kept the wiring loom, taped it up and
kept it with the engine. I didnt have the time to sort out the pieces
which were not required.
So - my recommendations are: 1. Consult a Mechanic - and ask him a few
questions as to whether it is possible to remove the wiring loom and to
"isolate" the ignition circuit alone - provided that you do not want the
electric start etc. etc. 2. Buy th eHAYNES manual for the particular
motorbike. They have a website at www.haynes.co.uk Their motorbike
maintainence manuals will have all the required information you need. Im
afraid I dont know of any websites that cover this area.
Best of Luck,
