Odometer Won't Roll Over By ellpee (Read 937 times)

[ellpee]

2011 Roketa, speedo (odo, actually) has never rolled over the way it should at 100 -- just sticks at 99.99999999999 until I push the button to go back to zero. Minor annoyance, but since I finally bit the bullet and removed the front plastics today, I have pretty decent access to the back of the instrument cluster. Is this likely to be something easy to fix? Have enough other things to do that I don't want another big project, but if it's just a matter of tightening a screw or something, might give it a go.

BTW, a fascinating exercise taking off all that front plastic. Something like 65 screws, nuts, bolts, washers, clips, etc., etc., etc. I suppose anything less would be Rattle City, but I know now why I've been postponing it, and I hope I won't have to do it again for a long, long time.

BTW2, all this plastic-pulling was primarily to FINALLY install a new left switch assembly, which I managed successfully and all now works as it should. Assembly itself was no problem, but the connectors were way the heck up under the plastic, no way to get at them without de-plastic'ing. We'll see if this one lasts longer than the original, which fritzed up within six months. Took me months to get the part, ordered it four different times and it was out of stock each time until just recently. Electricians out there, maybe a niche market opportunity for people who can re-wire/repair these things? Of course once I finally got the part it was cheap enough, but I'd have paid double to not have to wait so long.

What, nobody? Okay, putting it all back together now, will live with the odometer thing. Sad to say, broke off a couple bits and pieces of plastic in the course of this project. Not enough to replace the panels, but annoying.

Hi ellpee, did you check cable at wheel, maybe loose there, does it move the numbers when scoots moving?

[alleyoop]

The odometer is driven by little gears and they may be rounded off and not grabbing. They are pretty filmsy and most of the time the odometer is the first thing to go.

yes ellpee,that plastic is a pain ,i see why some guys buy new stuff later on,they made them not very easy to work on ,though if not for the plastic they would be very ugly,but much easyer to work on ,hope you get that speedo fixed

This one was dead on arrival, never worked right from day one (though of course I didn't find that out until I turned my first 100 miles). It starts just fine from zero and works its way up to 99.9999999, then won't turn the corner to 100, 101, etc. My practice has been, when I can remember, to reset it at that point. I don't much care about trip miles, really, except that I do use the odometer to decide when it's time to hit the gas station again.

Anyhow, everything's back together again (whew, what a job!), so it'll have to wait until next time. But yes, the speedo cable itself was good'n'tight.

did you say your gas gage does not work right I wonder I if will have same problem I am going to fill up tank soon though an find out if my gage is working ,let us know how it goes ellpee 8-|well I guess could be worse

[ellpee]

No, gas gauge has always been fine, although when it gets near the bottom I actually have pretty nearly a gallon left -- okay with me, margin of safety. Other gauges also fine, only minor problem is the trip odometer, hardly a big deal since the regular odometer works fine. I'm around 4100 miles on that one now. Maybe it'll refuse to roll over too when I finally get to 100,000 miles ... ?

[scot]

heheheheh .I got a feeling I may have the problem I,will let you know ,with my tank anyhow I have put gallon an it bealry moves up,soon will fill it up all the way with 91 octane

[ellpee]

My research (and 4000 miles experience so far) says 87 octane is fine. Chinese and some other countries use a different numbering system. But for a three-gallon fillup the difference is piddly, so whatever floats yer boat.

As to what the gauge shows, seems to me if it shows full when it ain't that's a bad thing, but if it shows empty when it ain't that's to your benefit -- you'll never run out of gas unless you ignore it for a LONG time.

[scot]

yes it comes up some so i figure it moves well that's good to know I know there gas it different an there 91 is like 93,so I guess 87 or 89 will work fine,we have what they call summer an winter gas they say ,I guess soon the summer gas will get hear ,I will fill it up soon then let you know I did hear that a certain amount is reserve yes I hear 210 miles to the tank ,so if one has issues with low then just check it with stick every  100 miles

[ellpee]

Wouldn't mess with a stick, just fill up to the brim a few times, ride to 100, compute mpg, use that going forward unless the engine has been running really badly. After many fillups mine is 75mpg give or take a bit (city vs. highway, flat vs. steep, time spent idling, etc.), so theoretically that's at least 225 miles per full Roketa tank. Therefore, when I hit 150 I start looking for the next gas station, trip odometer be damned. At 175 I'd start looking really hard, at 200 I'd start freaking out.

Octane, yeah, their numbers are higher. There's research octane (tested in a lab) which they use and which is higher, motor octane (tested with a real-life test stand and is considerably lower), and the US system, which averages the two. Much Googling says 87 is at least as good as Chinese 91. But again, for pennies a gallon, why not go with the super-stuff if it makes you feel more comfortable. Far as I know there's no down side, although maybe others will chime in with how it affects valves, pistons, fuel lines, or whatever.

Ellpee, the Jonway that I had would do that occasionally at 9.9 on the trip meter. I figured out that if I was gong highway speeds when it was supposed to roll to 10 it would. If I was going slow it didn't always click over.

[scot]

yes I just figured low at 210 ,,sunday tomorrow I am going to run the scooter so will fill it up ,I fugure if I gets half way up that will work to,i guess they say 1.5l is reserve wont show up much ,so mabey there nothing wrong ,I just learned the hard way not to fill something up that sits for 4 months ,with genrerater,so I just put about 14th of a gallon in it each month for running it ,now will see soon enough

[ellpee]

Naw, Dude, if you want to capture your real-world mpg you need to fill it up to the cap and then put some significant miles on it -- 100 or more, I should think -- and then fill it to the cap again. Miles driven divided by gas used and you know where you stand on fuel consumption, gauges be damned. Once you've nailed down your mileage you can play around again with only putting in a gallon or so at a time, but FIRST get that mpg number figured out!
