The bike has a very poor spark and seems to have a strange CDI (Igniter) box. See pics.
Does anyone recognize this? Looks almost homemade! The connectors also don't line up and 'lock' with the loom plugs, so clearly not an original part.
I'd like to put the ignition back to standard and I am now looking for a standard ECU. I believe the part number is 32900-17D00 for a 1989 Slingshot 750? Just wondering whether anything else may have been changed when this 'odd' igniter was fitted?
very interesting, Id try to eliminate any other factors before assuming its the CDI. get good plugs, make sure ALL contact points and connections are clean, trim the spark plug wires where it plugs into the coils and where the plug boots screw onto it
