Hi, I posted earlier about having a very fast bike, even without a running engine - speedo goes to max as soon as you switch on the contact.
I have now opened the cluster/breadbox and found the green and orange gear wheels partially without teeth and the bodies flexible. Think someone sprayed electro-cleaner in there in anger and the plastic is no longer hard. The little gear that drives it all has broken away and was stuck between the other gears. Not good.
I had an other speedo that I'll use as a parts-bin, but am stuck. All the gear wheels are easily removable except for the little one on the drive shaft (left of the orange wheel). Off course I don't want to damage it, as I need it, but wonder if it is an interference fit or is there something else going on.
Appreciate any experience out there!
