Spent most of the day fixing the wife's r1 due to an ignition coil going for shit.
This is the second one in 5k.
I am wondering what might be causing it?
The bike has about 53k on it and is stock except for some acro cans.
The first one burnt out in Cali last summer and #2 started to fail yesterday so I put in a spare we picked up down south out of a zx6 that will work for now.
The first one you could see it burnt right through the side of the plastic and rubber,the second one has no apparent burns but is just starting to go.
I even went and got a new digital multimeter to test them and in the end it was a water sprayer that showed me the bad cylinder.
My bike has over 120k and I have never had an issue like this ,I would have thought yamaha coils would last more than 50k.
