I can't help with the ignition or wheels, but 2 spark plugs per cylinder tells me the motor is a transplant from a newer bike. Is it fuel injected or are there carbs?Just picked up a 1996 900ss has msd ignition like car size and 2 spark plugs per cylinder. How common is that. Also polished or chromed factory wheels. No too hip on ducs as much as I’d like to be.
Not sure what these are pictures would help.tube inserts in the intake
