06 speedo - bugs n twigs

I have been having some problems with my stock electronic speedo lately.

4 rides ago it began working erratically. Would speed up then fall to zero if I let off throttle even though I was still going 15-20 mph. Got home found a long skinny twig jammed in between the front brake disc and magnet sensor. Pulled it out. The speedo then kinda worked next trail ride. It would record speed and miles for a while then did not record much saying zero when I was moving, etc. Then it really never worked much at all on the 3rd ride, and then yesterday my 4th ride in two weeks, it starts working again correctly for the whole ride.

Anyone had cable failures or similar speedo unit variations and symptoms of failure? The manual says the unit battery is out if the speedo suddenly clears all items to zero and that has not happened. What seems to be happening from the symptoms is like the speedo is breaking down internally or the cable is failing?

Dan says it may be a warranty item may be. Could the twig had put a 3 ride curse on it. Now it’s all better? Weird.

ok thanks, I put the same post on KTMtalk to see if anyone else had the same experiences

the sensor seems to be tight and in place, the magnet looks a hair deeper into the disc then the KTM's I saw in the field and the new Husabergs I saw at Motoxotica, but that maybe my eye. ,,,so i guess the gap is still right...though I thought that twig may have tweeked the gap some, but everything seems pretty solid down there. I have an enduro to run in two weeks. I hope it works for that race, meanwhile Dan has ordered a new cable, will be here in 3 weeks.
