I bought a 2005 VTX 1300 a few months ago and had a suspicion the speedometer was not accurate so today I tracked it with my gps and confirmed at 65 indicated on my speedometer, it says 55 on my gps unit. Is there a way to correct this? Has anyone ever run into this before?

Yes, this is a VERY common issue - probably ubiquitous. For unknown reasons virtually all VTX bikes and most Honda bikes are off between 5-15% on the speedometer. More specifically, the speedo reads 5-15% high. Yours is the worst I've ever heard of (10/55 = 18% high). This can be fixed using something called a "speedohealer". Search the interwebs and this forum for more info. However, be aware that fixing the speedometer using a speedohealer will cause the odometer to be off. Most VTX owners just recognize that this issue occurs, do the math in their heads to know roughly at what mph they are riding, and live with it.

Thank you for the info. The ride I did today clocked 43.7 on the gps but clocked 47 on the bike odometer, so they are both off a lot!

yes I did and I can not for the life of me see how this is possible and allowed

My initial suspicion is that this bike has been altered in many ways. The mileage is horrible.as well. I have a newer 06 VTX1300r in Maine and it gets 45 mpg this one only 30 but that is based on incorrect speed and mileage which actually makes it less that 30 mpg. I also found this engine's pair check valves have been removed and block plated. the carburetor has been altered as well.

is there a better jetting to use for use with oem pipes and pair valve removed other than the 195 and 55 jets

I decided to use an old smart phone. I downloaded a GPS speedometer app and it works very good. It keeps mileage in memory for trip mileage and is very accurate.
