I bought a R100RS that was in storage for 9 years, It went in good and running. It only needed a good clean and some TLC etc. On receiving the bike I checked compression and spark which was all good before I striped, cleaned and soda blasted it and high pressure washed it. Now on reassembly I found that I had no spark, I then fiddled around with the wires and got spark again. I later rechecked the spark and then there was once again no spark???? Not good, fiddle, fiddle spark, leave it a while no spark. AGH!!!! Remove the front cover, top cover and found the 3 pin plug connector from the ignition trigger assembly was not connected properly. Connect and great spark. Put it all back together and good spark. Leave it a day and rechecked NO SPARK!!! F*#@ &! Hell WTFH. Now here today I have stripped everything again, remover top and front cover, rechecked the connections etc no spark. Checked in the manual it’s a battery and coil triggered ignition by transistorised electronic system using Hall-effected transmitter. Now here I must tell you that I am absolutely hopeless with anything electrical and also don’t know the names of most of the components. I am not trying to start the bike at this stage but am check to see that all is good before final assembly and fitting the fairing etc. I need help to do a step by step test and check, advise on what special tools. I do not have a multi meter tester and most properly won’t know where to set if for what. Very frustrating. Thank in advance.
