Sport speedo change

[Riggins9]

Hi there,has anyone changed a speedo on a sport? How do you get the trip meter knob off,I've tried to pull it but I don't want to break it,so if anyone has done it before please answer this post.cheers Gary

if you mean the big MMB, that knob has left-handed thread, but forget it - nearly impossible to remove, and not worth it, either.

simplest and most accurate: get a bike thingy, perhaps from Sigma, one with illumination for a few $$, stick it where the worthless clock is/was.

There is a lot on the topic in the archives, both for the speedo and the tach which is much worse.
If you can afford it, get one of those all-in-one instruments from Stack or Motogadget. Looks much better, works as a first class instrument should and displays more info as well.
Much cheaper but of acceptable quality: Acewell.

And then there are a number of digital speedos for motorcycles out there, very small and accurate.

hi there bill,thanks for your help,my finances may run to a acewell clock,are they hard to fit?

[Bill Jurgenson]

no, not at all. magnet pickup just like a bike speedo. Acewell offers a brake rotor substitute bolt with magnet head: nice.
tach part connects to minus pin of the coil; very easy.

My trip-meter broke, the shaft fell out of position, and the knob became a bit lose as well. I then had to break the knob in to pieces, so I could open up the speedo-meter. Then I could put the trip-meter in order.
After having put the whole speedo-meter together, I made a new "knob" that I glued to the shaft of the trip-meter so it could be used as before.
