Speedo clock out at 30mph its showin 34mph

[madbikerbev]

Hi every1,

one of my main problems is my speedo being out, when im doin 30 it shows 34 and so on and so on, at 90 it shows 75, which nealy got me in trouble luckily my stepson was riding with me and flagged the speed.

any ideas on this, ive tried a few thing but dont know where to go next. except for buyin all new clocks, cable and drive.

Hi Bev,

I’d begin by checking the cable which is an easy
job to do… But the Haynes manual reckons that
‘special instruments’ are required to check the
speedo, and suggest you take it to a Honda dealer.
See page 9.9 in the link below.

Bike speedo's normally run 3-4mph faster
than the actual speed...

But one of the most in demand items for older NTV’s is the
clocks….If all else fails you may have to invest in decent
second hand ones…

I would try cleaning & oiling (sparingly) the inner speedo cable first. I had a friend with a Honda CB125RS with similar problems, oiling the cable on her bike helped & a new cable solved the problem completely.

It's strange how a worn or damaged cable causes this fault.

Hope this helps.
