I have a 86 GS550es not getting any spark. I have replace the signal generator and checked the Tri-Igniter but still no spark.
Any ideas?

Or buy a Haynes http://cgi.ebay.co.uk/Haynes-workshop-manual-Suzuki-GS-GSX550-4-valve-Fours_W0QQitemZ280244885273QQihZ018QQcategoryZ122275QQtcZphotoQQcmdZViewItem?refid=store

You could consider a Boyer-Bransden Electronic ignition conversion kit. They were popular on this model owing the unreliablity of the OEM system
