Chingrish and Speedometers

[2door]

Okay, so I got new speedometer for Christmas and installed it yesterday.
First I had to translate just what the instructions were telling me. See attached page from instruction book. There seems to be a conflict between what they mean by "right" and "left".
I tried it on both sides and it doesn't seem to matter however.
Went for a ride and the thing tops out at 11MPH. Won't go any higher. Oddly, based on known distances the odometer seems to function correctly. I know the bike will easily carry me 30MPh and it was running great yesterday in the cool weather.
Anyone have any experience with the Bell speedo? Oh, yeah, I tried it with the engine off, downhill and pedalling but the 11MPH was still all it would show. Rats!

I had another brand of cheap speedo it wouldn't go over 18 mph. I then went out and bought a WIRED sigma speedo, cost $20 but is rated for up to 50 mph AND it's been test to work up to 125mph by some vintage motorcycle enthusiasts. It's never let me down and is darn accurate. I can't recommend it enough.

Yep very similar, I'd recommend going with the 800 level or higher, those are the levels rated for 50 mph or higher.

Wireless speedos are a bit of a problem due to the interference in the ignition. Even the wired ones can have problems due to the ignition. I also use a cheap Bell speedo but it is a wired one. I also had problems with it until I replaced the plug and plug wire. It would read speed fine but it would reset itself all the time so I couldn't retain the odometer reading. Once I changed the plug and plug wire no problems.

Thanks Ghost,
Yeah, I know about the plug and wire issue, mine are both upgraded and I've tried this one with the engine off, pedaling downhill. The speedo will top out at 11/14 MPH, reset to zero but the odometer keeps counting. Weird. I think I'll take Shoe's advice and try the Sigma product. I'd like to find a good old cable driven unit and forget about the fancy, but often unreliable electronics. Someone posted a link a while back for a source for a really nice looking cable drive speedo but I can't find it again. If he or she sees this I hope they will repost here. Thanks a bunch.
