Hi, I have a VFR 800 Fi with a malfunctioning speedometer and would appreciate some advice on how to fix it. The speedo is OK up to about 40 mph then it starts to bounce about erratically, when I get above 40 mph. I have already replaced the nylon nut that connects the speed sensor to the sprocket bolt. The battery and charging system are fine. I have also determined that the correct voltages are present at the speedo sensor and at the instrument cluster. There is continuity in the pink wire running from speedo cluster to the speedo sensor, and I am getting a fluctuating voltage (between 0 and 4.8V) between the pink and green/black terminals at the back of the instrument cluster when spinning the back wheel. Following the advice in the Haynes manual it suggests that the fault may lie in the ‘speedometer or the instrument cluster printed circuit board’. Has anyone else had a jumpy/erratic speedo that was due to defects in the speedo or PCB?
Guest posted a topic in Maintenance GuidesG'day group. New member here who recently added a nice 5th-gen VFR800Fi to his stable (my other bike is a 1991 Yamaha FZR 1000). Several things about the VFR are new to me, including Honda's use of FI versus carbs and the fact that the rear axle is suspended via spindle secured to left swing-arm only. THAT leads me to ask what most use to raise the rear Viffer suspension for maintenance work (such as chain lubrication). Obviously, a conventional fulcrum-style rear axle support stand (such as I use on my Fizzer) won't work. I presume the correct answer would be a generic motorcycle 'lift jack' that fits under the lower frame and raises the rear wheel off ground, but thought I'd toss the question out for general review since some of you may have ideas I hadn't thought of.
