I've read reports of intermitten problems with the nuetral light staying on. And maybe I have got this problem, interestingly it just started after my first service (1000km ), so I'm wondering if the dealer could have cause the problem. The light did go off on its own once.. but now its stuck on again. Anyone know where this sensor is? The dealer changed my front sproket ( from 16 to 15 ) I wonder if a sensor or sensor cable could have been damaged? The bike has about 600 miles on it. Any tips on what is wrong, is this common?
