Here's what I was facing in the garage this morning...
Makes it really hard to work when it's so cold. My fingers were so numb it was all I could do to keep hold of anything. It did get up to 30°F though and I got all of the wiring in the headlight bucket connected up... except for my new indicators. When I got this bike it didn't have any indicators so I'll have to take a look at the wiring diagram to see where they plug into the circuit. ?? I'm terrible, I have all these grand plans to get things done in the evenings after work, but after dinner I'm down for the count.
So, as promised, here's a look at the worm...
and here's a look at the gear...
The gear looks good to me, but the worm looks like it's been eaten away. As DirtyDT suggested there are slots down where the speedo cable goes so I'm going to unscrew that "pegged bush" (as indicated in the manual, guess I should've started there ) and (hopefully) get the worm out tomorrow for closer inspection. If I can clean it up well enough I'll use it otherwise it's about $15-$20 to get a new one.
Thanks again for your advice you two! It's much appreciated.
