What is your preference for good ignition systems? What options are out there for the LT-250 & 500?

If you want to keep it simple use a stock ignition and open your plug (BR9ES) gap .002 at a time until it starts to miss. If you have to run .014-.020 then your ignition is week. Try to see about getting a newer set up thats not 25-30 years old. If you want everything you can get msd is the way to go but you will need alot of dyno time. Our 250r's stock 25 yr old ignition is week but a new stator and flywheel you can run .035 gap.
