Hi everyone-- i have just picked up a 1980 honda c70, but the speedometer glass is broken. I'm going to cut out a new plate of glass, and will epoxy it in. however, the gauge has been exposed to a little water, and i'm wondering if i shouldn't put some oil in through the bottom of the gauge before i reinstall it. it was working until a few days ago, now i put it loosely on the cable and it doesn't want to read... it just clicks around the gauge... maybe i need to tighten the screw?
any advice much appreciated.
