Definitely! When you put a larger or smaller tire it will effect it and so will changing any gear ratios. The speed- o- meter is calibrated for a specific tire size and a certain gear ratio and anything that deviates from that will cause the speed- o- meter to show faster or slower depending on the change. Think if it this way a 16" tire will travel farther in one revolution than a 14" will. Therefore if your car/truck came out with 14" tires and you put 16" tires on it then the speed O meter will show you are traveling slower than what you are. The opposite applies if you downsize. Changing differentials that have a different gear ratio can also affect it. It's a good way to get a speeding ticket. If you put smaller tires on one then the speed- o- meter will show you going faster than you are and it will take more RPM's to reach the same speed, thus causing it to use more fuel.
If you are going to change the tie size or gear ratio very much I would suggest investing in a good Radar Detector! Good luck.

There is a little set screw that stops it from coming out. remove the set screw then I believe you have to unscrew it.

Speedometer off


Over the years I have had many complaints of the speedometer being inaccurate, few times has it actually been the case, about 5% I would say. You can have the speeds checked for accuracy by any dealer using a known good vehicle speedometer pace car, done the test dozens of times. Normal speedo accuracy is plus or minus 3 MPH.

unfortunatey you may not be able to fix this, speedos generally run from a sensor or cable at the front axle, and rely on the rotating wheel, and are not generally able to be calibrated.

Well i'm going 60 mph but my speedometer read 70 plus for avery mile that i travel the meter read 1 1/3 so my car is gona hit 1k if i still friving like that?


In most cars especially those older models, the speed sensor for the speedometer is located in the transmission. Check for physical wear on the cable that leads from the transmission to the back of the dashboard. If you have increased the size of the tires dramatically, the actual car speed would be slower then the speedometer. Either the components responsible for measuring speed (speed cable, dashboard, speedsensor) is damaged or tire size or transmission parts or the transmission itself was replaced.

If the speedo gear is in the front wheel a different wheel would have different gear and mess up the speedo but I'm thinking the gear wouldn't mesh with the old speedo cable teeth.Check a shop manual for stock number of teeth on rear sprocket and tranny sprocket,that will tell the story.While your at it check the stock wheel size compared with what you got.Of course it could be bad speedo.There's springs in there that run needle, so?Maybe borrow one and try it out.Good luck.

WHY? Accuracy. Most of the Harley-Davidson motorcycles I've owned have had fairly accurate speedometers, but it's very common for the import bikes to be off by a considerable margin; the V-Strom is no exception. Realizing that my speedometer was reading higher than my actual speed, I cranked up my trusty handheld Etrex GPS and found that the stock instrument was off by a consistent 7.7% (when the speedometer reads 70 MPH, actual speed is 64.6 MPH). I figured that I had four options to deal with the problem: 1) ignore it, 2) watch the speedo and "guesstimate" my actual speed, 3) install an auxiliary speedometer, or 4) install a correction device.
Options 1 and 2 didn't much appeal to me. Installing an auxiliary speedometer is certainly a viable option, as some bicycle speedometers are very reasonably priced and can be calibrated to function with respectable accuracy. I was surprised to find a newSigma Sport BC500 unit on eBay for only $10.95 plus shipping, so I decided to check it out.
SERVICE. N/A. The eBay seller shipped promptly.
INSTALLATION. A piece o' cake, and one that could be accomplished by just about any owner. While the installation instructions are for a bicycle (go figure) it's not difficult to modify them for use on a motorcycle. The first order of business is to measure the circumference of the front tire and program the results into the unit; the measurement must be precise so that the readings will be accurate. The unit fits into a base that is easily attached to the handlebars with a rubber O-ring and a lead wire that is attached to a magnetic pickup. You'll need to find a way to attach it to the lower fork leg; since I only planned to use the unit for a short time I secured it in place with a heavy rubber band. It also comes with a magnet that's designed to attach to one of the bicycle's spokes. Since it obviously won't work on the V-Strom's front wheel another magnetic source must be used. Off to the local Radio Shack to pick up a pair of tiny rare earth super magnets ($1.89/pair, part #64-1895). These magnets, though very small--about 1/8"--are very powerful. I fit them into the head of one of the front brake rotor bolts, where magnetic force held them in place nicely. Here's how things looked;
sigmasportpickup.jpgRESULTS. Pretty darned good. Because the magnetic pickup detects only one pulse signal per revolution (the V-Strom's speedometer registers about 80 signals per revolution) there is a small lag in displaying the speed but at constant speed it's very accurate.
Worth the money? Absolutely. I don't plan to use the unit permanently, but it's an incredibly inexpensive way to provide an accurate speedometer reading. At less than $20 for the entire setup it's a heckuva deal!

ABS brake module sounds like a motor running and won't stop unless battery is disconnected. what is fix?


I would pull the fuse for the ABS hydraulic pump and then put it back in and see what happens. Don't ever recall a pump running. Dealer may need to hook up scan tool for diagnostic fault codes, DTCs.



Principles of Operation
The ABS control module receives wheel speed readings from both front wheel speed sensors and the rear differential speed sensor, and processes this information to determine if an ABS event is necessary. The wheel speed sensor electrically senses each tooth of the ABS sensor indicators as it passes through the wheel speed sensor's magnetic field.
The ABS control module continuously monitors and compares the rotational speed of each wheel speed sensor indicator and, when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper(s). This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS control module returns the solenoid valves to their normal position, and normal (base) braking resumes.
The ABS control module is self-monitoring. When the ignition switch is turned to the RUN position, the ABS control module will do a preliminary electrical check, and at approximately 20 km/h (12 mph), the pump motor is turned on for approximately one-half second. Any malfunction of the ABS system will cause the ABS to shut off; normal power assisted braking, however, remains.
Inspection and Verification — Scan Tool Communications Check
  1. Verify the customer concern by carrying out the Drive Cycle Test.
  1. Visually inspect for obvious signs of mechanical and electrical damage.

Have you called transmission place? Did they also install it? Ask them if they changed speedometer adapter, and mention the difference in speed.

you might need a new speedo cable but if its a sensor you could need a new sensor and that might not be cheap.
