Sppedometer error

[baylensman]

okay we all know that the RSV speedo's are inaccurate. So that leads to two questions.

 

1. If the speedo is off is the odometer off?

 

2.Is there any way to adjust the dang thing to get it closer?

 

The first question is about figuring fuel economy, I guess a could Google map the route and see how close it is.

The second is about drivability, am I keeping up with traffic that is going to fast or am i doing the limit?

 

i went past a school zone with one of the radar timers that shows your speed, it is active 24/7 the slow down lights only come on at certian times. the other day i held the bike at 60mph almost rock steady and the radar showed 43mph thats a little over 40% error.

That seems like a lot more off than I have heard on a 2nd gen. As far as using the radar timer, you really have to make sure you are the only traffic on the road to get an accurate reading. A truck or SUV a ways behind you can get a reading because he is giving a stronger bounce back of the signal than you are on your bike, or at least that is the way it is on my 1st gen.

Search speedohealer or something like that and you can see what it says. Not sure about the odometer, but you could probably get a good comparison with mile markers, especially the ones that have the tenth mile signs between the mile markers.

I think there was a problem with that school zone radar. I've never heard of one being off that much. They are typically off about 7%. Some of us installed the Speedo Healer to correct it. Very simple to do. As for the odometer, yes, they are off also but not the same amount as the speedometer. They are usually off about 4%. That means that when you correct the speedometer with the speedo healer, it will be off the other way about 3%.

Throw a GPS on it and clear the trip. Make a trip around somewhere and check you GPS and your odometer.. My 2nd gen @ about 75 indicated is 72 on the GPS. Never paid much attention on the actual miles. When I ride with my buddy he has a Heritage Softtail and his is reading a needles width under 75. thats just sort of our highway trip speed. I set mine @ 75 and we run along.

So Freebird, your telling me the speed reads faster and the milage will actually be LESS than what I have traveled? Oh my, that really makes the MPG suck.

On my 2006 RSV, the speedo is off just shy of 10%. At 70 mph indicated I'm actually doing 63-ish mph, or at 110 kph I'm actually doing 101-ish kph. I generally use my GPS speedo when riding, its easier to see the numbers at a quick glance and is more accurate. We have those speed radar announcers around here as well and it shows the GPS being accurate.

 

I had the SpeedoHealer on the bike, and while it made the speedo accurate, the odometer then noticeably suffered under-reading the distance by 8%.. I had since removed it, prefering an accurate bike odometer over speedometer.. I just got used to adding 10% to the speedo to keep within the legal speed limits if the GPS isn't mounted.

I second using the speed reading on the gps...especially for cross-border travel.

 

My bike is in KM/hr and when we are in the U.S. I set the gps for MPH. Even in Canada, I'll set the gps to KM/hr and use that to see what my actual speed is.

 

My speedometer is off by 8-10%, which isn't a bad thing when you are in a school zone (so you go slower than the posted limit) or in a speed trap zone.

I just looked up the SpeedoHealer and am curious as to how it is installed. Just a quick high level overview.

[Freebird]

Very simple plug and play. There is a connector under the left side panel. You unplug it and place the speedohealer inline with it. If I remember correctly, there was then one wire that hooks to your battery but I may be wrong about that. I installed it a long time ago. There are dip switches you set depending upon your percentage of error.

Thanks!

There are dip switches

Hey I resemble that remark.

well the odometer was off by 5 yds over 1.5 miles according to the GPS. i'll hit the speed trap with both my car and the bike again this week and see

I used a gps for speedometer but got tired of having to take the thing off and remounting it when I was out of sight of the bike so I bought the Speedohealer and corrected my speedometer with the gps using a correction factor of 7.9%. Now the odometer is off a little but if I want to check my mpg, I just add back 7.9%. The odometer was fairly accurate to begin with.

Sppedometer error

That would also be a sppeling error?

(Sorry!)
