For XF200, XP200, and Konker 200 owners

Looking to see how accuate the speedometers are for you guys. Mine is reading way off. I put a bicycle speedo on my XF200 to get a more accurate reading of speed/distance. I was driving mine up to my Mom's house with my wife behind in our car and she said that I was only going 55 mph....and backing up traffic. I was showing 64 mph on the bicycle speedometer but 70 mph on the Qlink speedo. I can recalibrate the bicycle one but I'm thinking that I got a speedo intended for an XP. Does it stand to reason that a XP speedometer for 21" wheels on a 17" wheeled XF would show a higher mph than what I am truly traveling? Is anybody else having that wide of a margin between indicated and actual speed?

For a few months i thought my bike cruizes at 90km/h. On my first long trip (Kunming to Chengdu ~1200 km of nice Chinese roads), I kept missing my planned checkpoints. Checking with the GPS I found I was going 62km/h!!! Oh well, I had my camping gear on. Changing to more street profile tires next time..
Oh, forgot to mention, I have a Shineray XY200GY-7. Konker 200, i think the original manufacturer is Kinlon? I thought my bike is comparable.

It's the rebadge Qingqi QM200GY in Canda

Looks like your speedometer is set for a 21" front wheel. Putting a 17" wheel makes it show a faster speed. The math is also consistent with the numbers you gave: 55mph*(21/17) = 68mph

Is there any way to adjust the speedo? On the galaxy XTR it's a digital speedo and it can be tuned with a botton on the underside.

No way to adjust the speedo, felix. It's driven off the front wheel via cable. There are ratio adjusters available but at a pretty high cost compared to what I can do with the bicycle speedometer. I checked the XP and XF parts list and they show the same part number for the speedometer gear, 37200-SM10-0000 but slightly different numbers in the note section. The XF is F47A-17 and the XP is F47-17A.

Ok, how about seeing if you can open the speedo and make a new piece of paper to go behind the needle, with numbers in different locations? The needle will still be in the same place but you'll have changed the numbers to show correct speed. You can mark a few points of the needle at true tested speed, then figure out where the other numbers go between that.

- or just simply do what I have done with the Kinlon speedo (which is not very accurate and the numbers cannot be seen anyway if the sun is shining, because of reflections) - just check with a GPS (might not be needed in your case from what Felix said:55mph*(21/17) = 68mph) and mark the relevant speed limits, ie 50 kph, 60kph, 80 kph and 100 kph on the face of the speedo glass withsome paint or nail varnish. Or whatever they are in your area. That's all you really need to check on from time to time, the rest is arse, eyes and ears not speedo.

Hey! That's a pretty good idea there felix. I have had the speedo open before (can't remember why) so it should pretty easy to do.

Jape, the numbers are actually pretty easy to see on this bike. I don't have a GPS as I have no use for one..yet. I just think that Qingqi could have sourced a set of speeometers that would have covered both applications. I know Konker (in Canada) sells the bike with the 21" wheel option to switch out if desired. I haven't heard yet which configuration yields the correct speed. I can also go with a Vapor speedometer and replace the whole shabang.

Hey guys not to throw off subject but i own an 07 qingqi 200gy(qlink,konker,etc). And can't find a definative answer on the valve specs. Anybody know that one? She purrs like a kitten but i always like to check after the first 1500mi or so.

This seems to be the best calculation of what the down-to-earth rpm/speed is:
Attachment 2386

Enjoy!

Valve specs should be .005(in) on both. Dont quote me on that but it should be no less than that.

The valve specs are 0.06-0.08 on the intake and 0.10-0.12 on the exhaust, the Speedo gear on that bike is prone to failure, so is the cable. The parts are different and the XF is F47A-17 and the XP is F47-17A….that would be 17”and 21” respectively.

Check the gear for smooth operation the speedometer should be accurate across all speeds if it is generous then it would be showing mph as it comes to a stop. Not spinning freely can cause false readings it has to be taken of and inspected.

If they are not accurate then it would be that the actual gauge is not metered to match it but it should be consistently off on all of them or it is then a mechanical failure and if its the gearing and or the cable it can be progressive and with variability.

I have a service manual...that's were I get the information.

MJH,if it's true that there are different speedos for each style of bike then I got a XP one rather than a XF. I did look at the part numbers for both style of bikes and they are the same. There is note section that show different numbers, the ones you listed. Why wouldn't the part numbers be different? Also, if the gears or cable were binding at all I would have a lower reading rather than higher.

Based on the numbers that felix gave I'm sure Qingqi installed the wrong speedo.

Different speedometer gears not the gauges themselves, they have different numbers my part book says F47-17A and it’s the speedometer gear for the XP200 yours would be F47-17 less the A? Isn’t yours black on your bike?

Who knows maybe they crossed them in the paint shop of the factory?

Oops, you're right. It's the gear box not the speedo. My bike is at my Mom's for winter storage so I'll have to check it out when I get back there. Maybe there is number on the gear that I can locate.

MJH, I'm not challenging you, but inquiring as to what manual you have, and where did they get those valve specs. I checked the gauges on the assembly line during a visit to QingQi and they were 0.06-0.08 intake and exhaust. That's a rather large discrepancy on the exhaust side :confused1:. I would be interested to know the actual spec given in the Suzuki DR200 manual.

Thanks for the insight.

Cheers!

Hello my friends!
In Brazil's manual is specified:

Intake valve clearance 0.08 ± 0.02 mm
Escape 0.10 ± 0.02 mm.
It is the same as
Admission 0.06 ~ 0.10 mm
Escape 0.08 ~ 0.12 mm
So I think all are correct :popcorn:
