    Looking at the schematics, I don't see how the turn signal relay could do this. But, it still seems to be the most likely cause??

    The cancel circuit is at least partially working if you can push the turn signal button and cancel the turn signals. So it is not completely hosed. The circuit needs the speed pulse signal to work automatically. I don't see how that could have changed?

    Because nothing makes sense here, I would swap back the original relay first and see what happens. You changed the relay (flasher) that is in the nose of the fairing, right?

    Rather than waiting for a replacement, I modified my original relay to work with LEDs. You have to cut it open, remove the circuit board inside, and cut a trace to the chip (I think pin 7). Then RTV it back together. If the relay turns out to be the problem, and you choose to modify yours, I can help you do that.

    Good luck!

    Thanks, I'll try that this weekend, if the factory one works again then I'll look into your mod. Yes I changed the one in the fairing, sometimes it's a pain to shut off the turn signal, I almost have to push it to the other side and hold it in, wierd.
    Thanks for responding.

    I put the factory relay back in sunday and then of course it started to rain, I'm going to test drive tonight and see what happens, I'll post up tomorrow.
    I also checked the thing inside the neck of the bike, sorry forgot the name, my service manual said to check that, not to hard to get to and everything looked healthy. The bike only has 2200 miles on it.
