Broken Speedo Options for your Guzzi
Don't want to replace your speedometer with another pricey poor quality unit? The white-faced Veglia's seem to be more reliable and are rebuildable by one of the many speedo repair shops in the U.S., such as Palo Alto Speedometer to the tune of ~$200+ USD. The ITI's are disposable for the most part.
If you'd rather replace with a higher quality unit, the easiest solution is to purchase a 3-1/8" AutoMeter electronic speedo (1487/black -OR- 1388/white) per below:
along with an Acewell Speed Sensor Cable (ACE-S4 ~$10) from ElectroSport as shown below:
Drop in, wire up, calibrate and go.
Other solution:
Thanks to M Khan below for his words and pictures for his soultion below using a VDO unit.
If you have a ITI, it's probably best to just replace, as they are driven by a nylon gear that is prone to low-mile failure, and is typically not easily repairable or replaceable:
M Kahn chose a VDO "because of their superior workmanship and the beautifully simple dial. This dial has miles only and is instantly readable. It is good for a bike because it is sealed against moisture and even ozone." It's available in black (VDO 437151) or white (VDO 437201):
Installation:
Install is fairly simple. All you do is to uninstall the defective speedo and insert the new one. The original rubber ring which holds the old speedo will also hold the new one, and a small amount of lubricant (even water) is best for removal/reinstall of the new unit:
The original outer cover can be used on the VDO:
The cover screws cannot be re-used. You will need to purchase two (2) 12-20 bolts and matching lock nuts - do NOT over-tighten. The heads of the screws need to be filed in order for them to fit the groove of the VDO:
Electronic speedos require electronic signals. The VDO sender which costs ~$80 will not work. A GM/Mopar Speedometer Hall-Effect Sender -16-Pulse (as shown below) happens to fit and work. They can be found online and on eBay for ~$30.
Remove the speedometer cable completely from the bike, and fit and tighten the GM sender to the transmission where the cable was removed:
You will need to source and run wires to from there to the back of the speedometer. The connections are as shown HERE.
This is what it looks like when completed:
The chrome ring can be re-used from the stock gauge and placed on with adhesive should you decide (MPH memory option showing):
The last step is to calibrate the VDO, and can be done in an Automatic or Manual setting with the included instructions.
