Well i was on my 954 going atleast 80 on I95 and the next thing i know i felt my chain broke. I'm lucky that nothing happend to me and glad that i have another bike. I went to turn on my 954 and notice that my rpms is where it needs to be but my speedometer isd showing 6 and 5 mph. What dous that means?

 

just unplug it and plug it back in

 

might have knockedthe speed sensorwhen you were changing the chain, or when the old one broke, bobjoes got the right idea to start with.
