Speedo fluctuating wildly
Not sure why this has started to happen but especially above 30 mph the speedo fluctuates anywhere between 5 and 20mph it basically flails about wildly...what could be causing it?
Re: Speedo fluctuating wildly
One of two things, knackered sensor or knackered speedo.
Try cleaning the sensor first and check the wiring, if that doesn't work change the sensor, if that doesn't work its either a new speedo or learn to live with it.

Re: Speedo fluctuating wildly
where do I find the sensor?
Re: Speedo fluctuating wildly
I believe its buried behind the rear wheel.

Sensor replacement is part of this: http://hondapcx.org/viewtopic.php?f=3&t=4373
Ignore all the gear stuff. It's a cover you'll likely have to remove the rear wheel to get at, two allen wrenches, and a standard hex head for the sensor itself.

Many thanks, looks way beyond my capabilities though.
