Happy New Year to all readers of the forum. I have a cbr sc21 from 1987. To show you the photos I am attaching the url of the sales announcement. https://www.subito.it/moto-e-scooter...st=1&spoint=ar. When I restored my bike I didn't feel like spending 200 euros on the four pipettes with the related cables. The sum seemed excessive to me. I replaced the high voltage cables with normal orange AT wires, connected to normal candle pipettes without the upper closing cap. Clean and reassembled everything worked normally. I never stop buying spare parts in excellent condition when they are at a gift price. I use them to further improve my hurricane. Last week I bought on ebay a thermostatic valve body complete with pipes, thermal probe, cap, two coils and four high voltage cables including pipettes at a cost of 50 euros. Today I picked up the package and to my surprise the material was like new. I disassembled the high voltage cables to replace the wires and reuse the original pipettes to then mount them on my hurricane and I realized that in the new pipettes there was, between the wire and the contact of the spark plug, a resistor. In the original old pipettes there was nothing. What is the intermediate resistor between the coil and the spark plug for? Are they SC24 pipettes? Has anyone ever tried to replace high voltage cables with normal orange AT cables? Is it not advisable to mount that resistor on my sc21? Thanks to those who want to answer me. A cordial greeting from Italy. Walter
