Default Analog Speedometer

I thought i would try one of the analog speedometers on my bike and see how it goes. As best as i can tell it reads about 10 mph fast. I base that on my FD with a Zenoah G430 and what i see on the Gear Rat . At 5500 rpms i should be going 18.41 mph. the speedometer says 28 mph. Just thought anyone else might like to know what i found out. My tech.is reading about right. I have a 1.125 dia. drive roller.

speedo is much easier to test than tach - have someone follow in car

The analog speedos are just cool and look good. I doubt they are 10 mph off.
Maybe not extremely accurate, like at 40 your doing 39 or 38 at worst. Watch out when you buy them as some offer them cheaper like some sellers on eBay but if you look close they are not in mph but kh.

ZipTie, I checked and you were right. I bought it from e-bay and it is reading in Kilometers. I checked a conversion table and it looks to be right. 30 Kilometers = 18.64 mph. Thank you

Awesome, problem solved on the speedo, yes you got tricked by a slimy supplier. They almost got me to just the other day. The KH ones are being offered like 10 bucks cheaper. I double checked cause I thought. Hey something's wrong here...notice how they try to hide the fact it's not mph.

Another trick is watch for ...ones with resettable trip meters and without on the analogs too. Get the resettable trip meter one its the same price or a buck more as its very handy.

As cautious as I am,I get ripped off too frequently on eBay due to my own greed, not paying attention to details or stupidity. eBay is a awesome resource and the service is usually fast but a buyer needs to read the listing in detail and read what they don't say as much as what they do.

FIX. Make a new MPH speedo face in adobe photoshop and print a new paper faceplate. The glass just pops off with friction, the needle lifts right off as its only held on with friction too. Someone should come out with a cheap 2.00 sticker that converts them. The face plates on the factory ones are cheesy looking with the racing flags anyhow.

I like your idea of a replacement face plate. Hope someone that has the know how will do it. I just use the fact that i am old to excuse my mistakes it works for me.

I use the same excuse just as of late, ill even use it in front of people now too...
All you have to do now is memorize the entire kh to mph conversion chart and make calculations on the fly. Hehee
