Hello all QT 50 owners. I was wondering if maybe we can put something together to test the CDI system. I don't know how well this will work but its worth a shot. Seems like some of us have been having some issues with the ignition at times (which i am having right now) The shop maunual tells you how to check the coil and the electrical but thats about it. Not much on the CDI components. If we can get someone to do a resistance check on the connectors on a bike thats running good, then at least we'd have something to go by. Thats if we get any readings. I'll see if i can do it on mine tonight. Should only take a few minutes. Mine runs fine on start but not in the run position. I'll test the two black boxes in the back of the seat and the wires coming out of the engine. If I post my readings can some of you do the same and we can compare them and see if any comonents are out of whack? Then once we got the info, if theres not a huge difference in them, I can post them on a site so we have them for future reference. There should be some type of readings on those plugs. Id shows to test the CDI in the shop manual but i don't see any resistance tolderances it shows just a picture. Hopefully some of you will want to give this a try. Thank you.
