1983 MHR 900 electric start.
Posted: Sun May 21, 2017 12:50 pm
I have a seemingly weird problem. My 1983 MHR 900 electric start engine runs somewhat ok with the choke out. Once I close the choke, the front (horizontal) cylinder dies. I know you're thinking vacuum leak. I did too and triple checked and overhauled the carburetor and it's mounts. I pulled the plugs and checked the sparks. The front visually seems to have a weaker spark. After checking and swapping the coils, I determined they are ok. Do I have to dig into the pick-ups, or could it be the Bosch ignition module? Can it be something trivial as the spark plug caps? I'm running NGK 5 Ohm with Champion L86C plugs. The ignition system is all stock. The bike sat for 10 years, well taken care-of and prepared for long storage. I'm stumped.
I'm thankful for all you suggestions.
