RZ sat for 10 years, speedo and tach don’t work now.
As the title states, bike sat for 10 years. I’m currently resurrecting her, but the tach and speedo don’t work. I think the cables are fine (seem to remember replacing the tach cable just before I quit riding her), so what is there that could go wrong on the cluster?
Thanks,
Mike

Spiders? The US spec bikes use mechanical tach and speedo. I was having trouble with mine and was looking for a replacement but when I took it apart it was just all busted up inside. Used Bondic, JB Weld and some patience and have it working. If yours isn't broken and, depending on where it was stored, you might have bugs.

Guess I'll have to pull the gauges and take a look, thanks.

Usually pretty robust. Let us know what your problem was. Sure it will help someone in the future!

Mine didn't sieze, but was making a nasty howling sound that I could hear over the engine. I pulled the cable and stuck the tube from a can of cable lube up the hole and gave it a good shot and the noise went away. Maybe doing that and letting it sit for a while will free yours up. Also check the drive tangs in the front wheel for the speedo, they can bend out of engagement with the speedo gear.

If the cables seized in the long storage and were highly oxidized, they may have broken when you ran the bike. Disconnect both ends of each cable and make sure when you spin one end you get the corresponding movement at the other end.

Well, both the tach and speedo started working after riding a few miles. Not sure if it was a common electrical issue of some kind or not.

Was the battery dead or low to start with?

Don’t think so. I used a new sealed home alarm battery, but after I bought it I charged it and my Ctek charger showed it was charged.RuZty wrote:Was the battery dead or low to start with?

With a dead battery they will start and run but the tach does funky stuff on the electronic ones, doesn't explain the speedo though. Might not be a bad idea to lube the speedo (and tach if it's mechanical) while they still work.

Replacment speedo cables are cheap and easy to source. Just get another one.
