Speedo fail
Written by kjp986 on 6/6/2010 at 09:02 pm

Yeah, I'd take a look at the cable. See if you can reach up from under the front
fairing to unscrew it from the back of the instrument cluster. If not, then
you'll have to take off the windshield and the vent behind it. That gives
perfect access to the cluster. Would be minutes to replace if you can reach it.
I got mine from Service Honda, and like I mentioned in my first post, the cable
came with a new O-ring attached. So no need to buy another. That wasn't apparent
from looking at the fiche.
Can't tell you how to evaluate your current cable, but the new ones are very
flexible. Almost like a length of latex tubing. I spun my old one with a drill,
and it seemed ok...
I ordered it on a Monday, it showed up by the end of the week.

I suspect something is a miss, but not sure what. I think you have provided me
the clue where to look - speedometer cable.

a quick story from a few weeks back. So I was riding out to Road Atlanta to
watch the AMA Pro races a little bit ago. Saturday rode out, spent the day, rode
back no issues. Sunday rolls around, and I'm headed out to the track when I
notice the speedometer and odometers aren't working anymore. Great, I thought,
speedo cable is shot. With many miles left to ride I started thinking about my
recent drop in gas mileage. I keep track of it on Fuelly.com, and since October
it has dropped from over 50 mpg nearly every fill up to under. Usually between
47-49 mpg. I started wondering if the cable was dragging, and bringing my
mileage down. Not actually affecting the consumption, but showing fewer miles
traveled per fill up. Thereby giving the impression of increased fuel
consumption.

turn signals manually, like the common folk! Oh, the horror! LOL! I resisted the
urge to immediately get a speedo cable on order, instead waiting until I could
tear it down the next day. Upon inspection, the cable was indeed intact and
functioning when spun up with my drill. So took off the wheel and found a
broken tab on the drive gear inside the hub. From the fiche I ordered a new
gear, and the two thin washers. I think they act as bearings. Probably were
fine, but they were cheap and I was already in there. I decided to go ahead and
replace the cable. 63,000 on the original, I figured it had served it's purpose.
Also a small o-ring for the bottom connection of the cable. (I found out when
they arrived that the cable comes with a new o-ring.)

was indeed dragging my mileage down, affecting my mpg. Also this was putting
added stress on the plastic drive gear trying to spin the cable, which resulted
in it's failure.
