On the 929. Mine has full erion exhaust, A powercommander and intake filter. Dont know if that will change it much. I have heard that what its reading is not correct by a long shot.

When you says what its reading, what do you mean? What is "it"?

NONE of your mods will have any effect on the speedometer at all.

From the factory they supposedly read about 4 to 5% high (ie: 4 or 5 mph at 100).

It depends on sprocket, tire size and wear. Mine IS 3% and it's been proven accurate all the way up to redline. 6th gear at 167MPH

It depends on the sprocket if you change it. From the factory, as in NO mods, the speedos read about 4 or 5% high, thats a pretty standard thing on bikes. Changing a sprocket makes it greater.

Why does that percent sound so little though?
I can swear mine is off much more than that. Either that or the people in my town really drive like nuts......lol

4 to 5% is not really little. And unless you have it checked, or at least have a car pace you or do something to get a good read on it, you really can't tell. Some bikes have been known to be off as much as 7%, but not more than that. Speedometers should be right on, but for a safety margin japanese motorcycle companies have thiers set 4 to 5% high.

All u have to do is wait and ask the cop how fast you were going.

Radar is not that accurate either...

You would be surprise at how accurate radar is. especially the laser

MANY states have a provision in their vehicle code stating that tickets cannot be issued when speed detection via radar is used unless the individual is travelling at 6 mph or more over the speed limit, to allow for radar inaccuracies of up to 5 mph. Likewise, some of these same states have a similar provision for all other types of speed detection equipment (inc. Laser), where tickets cannot be written unless speeds are in excess of 10 mph over the speed limit (11 or more), to allow for inaccuracies.

Radar and laser is accurate, however, the equipment must be maintained and calibrated on a regular basis because it does go out of adjustment, and that is why there is a margin of error.

Apparently YOU might be surprised just how inaccurate it can be.

I know there can be error. The radar and laser is very accurate when it is working properly, There is the Cosine effect which effects the accuracy more than the error in the equipment. the Cosine effect dealse with the angle of the road and radar. the object has to be coming straight on at you in order for it to be accurate. well guess what? if it is coming straight at you then it is going to hit you and that is where the most of the error comes in. That is why we cant radar people (accurately) while they are coming around a curve because the reading would be inaccurate. Im not trying to argue with u BTW Im jsut giving my 2cents. I know there is error in the radar but I know more of the error has to do with the angle of the radar.

Then why did you jump in and tell me I would be surprised how accurate it is? Now you agree that it can be very innacurate... Seems like you just like to argue.
