Question about engine/speedometer

[jonathanneely]

As most of you know  I blew my engine (yes I have not broke into it yet - a little scared to - I know nothing about engines and if I opened it up, I'd look at it and say to myself "now what?").

Is the speedometer connected to the engine somehow? One thing I noticed when it started knocking is the speedo completely stopped working. What's that all about?

[saxman]

Speedo is driven off the front wheel, tachometer is driven by the motor

[jonathanneely]

Then why would my speedo stop working?

[jonathanneely]

And tach continued working...

broken cable, or it may have same loose where it attaches to the piece that goes on the axle

The problems with your speedo and engine are totaly unrelated. I cannot imagine any scenario whereby one might influence the  other...............but I am open to suggestions

Hey sledge, do you think it could be the thronomister?
