Title: Speedometer error? Post by: z10 on October 12, 2013, 04:12:53 PM I went out for a ride this afternoon and for the first time took along a GPS to check my speedometer.
At an indicated 85mph I'm doing about 76, so the speedometer is reading almost 10mph faster than actual. How to I correct this? Thanks in advance. Title: Re: Speedometer error? Post by: BuzzKill on October 12, 2013, 07:18:03 PM I could be talking out of my butt, but I think alot would have to do with tire size. What are you running on the front? Also I don't think there is an adjustment, but again I could be wrong. My wifes bike has OEM tires I think, and hers indicates faster as well.

There are electronic fixes, including a GPS instead of the speedo. http://www.amazon.com/s/?ie=UTF8&keywords=speedohealer&tag=googhydr-20&index=aps&hvadid=9257532939&hvpos=1o1&hvexid=&hvnetw=g&hvrand=120723603229331885&hvpone=&hvptwo=&hvqmt=b&hvdev=c&ref=pd_sl_6cloaxj088_b (http://www.amazon.com/s/?ie=UTF8&keywords=speedohealer&tag=googhydr-20&index=aps&hvadid=9257532939&hvpos=1o1&hvexid=&hvnetw=g&hvrand=120723603229331885&hvpone=&hvptwo=&hvqmt=b&hvdev=c&ref=pd_sl_6cloaxj088_b) http://www.yellr.com/yb_home.htm (http://www.yellr.com/yb_home.htm) Title: Re: Speedometer error? Post by: wizard -vrccds#125 on October 12, 2013, 08:05:51 PM Thy are all that way. The only way to correct it would be a drive gear change and none are made. You can just go by your GPS as I do on both of mine. (http://vrcc.photostash.com/vrcc_19179/DSCF1775.JPG)
Title: Re: Speedometer error? Post by: R J on October 12, 2013, 08:55:43 PM I go by the GPS in all my vehicles. The Dodge pickie up is the closest to the GPS. There is only 2 mph difference in them. The Toyota Highlander is about 8 mph fast. Title: Re: Speedometer error? Post by: hueco on October 12, 2013, 09:14:28 PM My best friend is off by 5 mph. GPS reads 70 mph. Fat Girl's speedometer reads 75 mph. So on and so forth. NOW. I Know why I never got a speeding ticket. :crazy2:

I also use a GPS to verify actual speed for different vehicles, and it varies a lot. Title: Re: Speedometer error? Post by: Joevalk on October 13, 2013, 05:57:24 PM I fixed mine. 21" wheel. The speedo is rite on the money with a GPS :cooldude:
Title: Re: Speedometer error? Post by: z10 on October 13, 2013, 07:29:25 PM Well, then GPS it is. Really cuts down on my top end bragging though. :2funny:

" I topped out at 130 mph according to my speedometer". Title: Re: Speedometer error? Post by: Red Diamond on October 14, 2013, 10:36:58 AM No adjustment necessary for me, when I see 75, I slow down to 70. Guess that's why it takes me so long to get anywhere.
