If you send in the BME50 Ignition to be upgraded, you can also send in your Hall sensor and they will upgrade that with a better grounding system. I sent both of mine in about two months ago (the ignition & hall sensor) and they upgraded it and got it back to me in two weeks. That's two weeks from the time I sent it out and to come back to me, good service. Oh, and don't forget that you'll need a different spark plug with the Bosch cap, it will only fit the short 3/4 hex 14mm plugs, such as the Champion RCJ7Y or NGK BPMR6A. The Bosch cap will not fit the plug that's in there now used with the rubber boot. They have them in stock too if you want to get them from CH along with the other upgrades.
