Alright, just bought a Honda H100 that's been cafe racered, beautiful bike but still needs a lil work. The clocks are 80s ones, they're plastic and rectangular. I've got them off and tried dismantling them, but they just didn't want to come apart and I can't see any screws to undo. I figure this may be intentional so you don't screw with the mileage. Is there any fairly simple way I can change them, like buying an aftermarket generic clock (seen a few on eBay)? At the moment I'm thinking I'll make something/get something made.
