Speedometer variance

bacarudaguy · Feb 15, 2014

Noticed riding the other day that the speedometer is off by anywhere from ~2-8mph depending on speed... is this common or do I have an issue with my gauge cluster?

Also had a weird thing happen... glanced down to see the speedo fly all over the place real quick, then I noticed my trip distances had been reset... I may have to check the connection to the cluster to make sure it's tight. I was just in there and everything seemed ok.

Thoughts?

Do a search and you'll find about 240,000 posts on the topic.

It's pretty well established that the speedo shows about 10% over reality. It's easy to do the math while your riding, or there are various products to correct - search speedo healer.

I see that now... got post happy before I fully searched... kinda silly that they're that far off...

The bouncing of the speedo needle and the resetting of the trip readings is common with loose battery connections or the green connectors under the right side of the tank. Tighten the battery cables with a wrench or socket. Be careful not to strip the bolts.

Thanks... I pull the seat tomorrow and make sure everything is tight...

Honda never made any model read less than 5mph fast.

One could be Tech for Honda riding hundreds of models -
it's the built in psycho assumed speed that no one will notice unless GPS is used.
