I am still hunting for just the right Speedo and I have become curious about wether the speedo drives are interchangeable and if this would solve the ratio difference. It seems/looks like most Yamaha speedo drives are the same. The XS ones at least but I have seen others as well.
Surely some one else would have done this if possible.
Also it seems some have worked out the XS1100 ratio as 2.9:1 and the xs650 as 2:1 as most other bikes.
Yet some still claim to use any of the XS speedo's from Mikes XS with no problem.
I will need a new speedo drive and cable in any event if I stick with mechanical and now I see there is also adapters you can get that will vary the ratio to fix a speedo out of wack anyway.
Any advice would be appreciated.

Brett .........me thinks.... your miles ahead of anyone on that topic already. :)

I reckon if you can get a speedo drive to fit our forks and axle from whatever model bike speedo takes your fancy it will work
getting another speedo drive to fit is the challenge...............do you have make and model of other bike speedo that you want to fit?

I like the vote of confidence Jeff but I reckon the most I may have done with a motorbike speado cable is take the broken one off my bike and throw it in the bin.
Well lets start with the xs650 speedo drive Jonesy.
EBAY XS650 Speedo Drive (http://www.ebay.com.au/itm/XS650-Speedometer-Drive-Gear-1983-Yamaha-XS650S-341-25190-01-00-x-/121086082380?pt=Motorcycles_Parts_Accessories&hash=item1c314afd4c)
It sure looks the same?

Then I should be able to use this speedo?
Speedometer - Chrome Mini 60mm (http://www.mikesxs.net/product/03-0750.html)

Speedometer - Chrome Mini - 2.25" Diameter (60mm) - Black face, 0-220 Kilometers per HR for Yamaha 650's. Internal illumination and Indicator lights. (High Beam, Signal & Neutral Light). Resettable Tripmeter. Calibrated for 19" front wheel. 2:1 ratio.

problem solved, that speedo drive will go straight on, I've previously fitted an XS1100 drive to XS650 wheel, so doing what you want to do will be no prob
-
Thanks Jonsey,
I got this from posting similar question on the .com site
The 650, 750, and 850, all had the same ratio and can (and have been) be used.
I guess if I get the speedo that suits the 650 and a speedo drive that suits the 650 then I should get the cable from the 650!
-
It is becoming apparent that the XS650 (edit) speedo drive Ratio is the same as the xs1100 speedo drive Ratio.
See this one selling in Germany is stated for all models with a 19" tire ???
Speedo drive (http://www.ebay.com.au/itm/TACHOMETER-ANTRIEB-TACHOANTRIEB-SPEEDOMETER-SPEEDO-DRIVE-GEAR-XS-1100-XS-750-850-/251060571517?pt=Motorrad_Kraftradteile&hash=item3a74604d7d)
Anyway I have taken the plunge and bought this speedo
Speedo (http://www.ebay.com.au/itm/190969406423?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649)
It runs gear ratio 1400RPM @ 60KMPH or 2240RPM @ 100Kph which I understand is the same as the XS650 and the same as the XS1100.
Still need to purchase the speedo gear and speedo cable. Thinking I will get the xs1100 ones.

hey Bretto
I have a couple of these drives in stock if you want one
;D

That would be great Bryan, make sure you put your return address on the package because your on my Christmas card list this year. Misses threw the last package out before I took note.
Do you still have my address?

I think there an echo in here ?
Hey bretto I got one in stock too

I tried an XJ900 18" wheel on my XS1100, only a 15mm axle so had to use the 17mm XS speedo drive, the XJ900 speedo drive I stripped and compared to XS11's, by eye they're exactly the same pinion gears inside, you can punch out a pin or something from memory to see, the 15mm XJ speedo drive I swapped to an fzr750 wheel on the XS11, hollow 15mm axle, wide alloy hubs thin as eggshells, there's bearings to swap axles forks etc.. the yamaha stuff can mix and match all sorts of parts, kwaka stuff can also match yammies and some suzuki stuff but not much, but hondas are deliberately made not to match any any other bastards bikes. But the 18" wheel, ran the same drive as a 19" wheeel, so figure that.. down to the tyres low or hi profile, radials are low as, the 17" radial fzr wheel read just under 10 k's high with an XJ/XS speedo drive but on my XS11 speedo the faster you went the less the error checking with etrek gps taped to the tank. Speedo accurate enough with 18" 110/80 which is lower than 100/90 but both tall ply tyres, in other words sfa between them

not sure Bretto
PM me your addy to be sure

Thanks PG, I would love to get my head around what swaps with what!
Shit Jonesy now I have to choose who gets to send me one and it has confused the hell out of me ???
I even made an offer on ebay for one and the bugger accepted my first offer and I have had to retract the bid. That guy will be pissed ::)
I will pm the address :)
-
Brett, I've got concerns regarding the drive ratio which is "Calibrated for 19" front wheel. 2:1 ratio."
All the XS11 drives are 2.9:1 so there'll be a marked difference in the reading from this speedo, as in it'll read about 1/3rd fast,
or does he sell a matching drive unit to suit this speedo??
-
Yes Errol it is very confusing as some will say the 2:1 works and I was about to jump on that with the 650 drive but only by luck I ended up getting the 2240/60 speedo which with a little more reading it seems that is the one for the XS1100 and the XS650-1100 all have the same speedo drive.
So as far as I can tell from the info given here and .com is that the 2:1 SPEEDO Mikes XS sells will be out of wack on a 650 and the 1100.
At this point I think I will just have to wait and see. Last resort will be getting a speedo drive adapter to vary.
-
Hey Brett, I just wanted a Christmas card that's all
just to add to the confusion an XJ 650 speedo drive and speedo for that matter will go on an Eleven as well
-
Brett, did you find this thread on Dotcom?
Steve's post at the end explains it all - CLICKETY CLACK (http://www.xs11.com/forum/showthread.php?t=39830&highlight=speedo+ratio)
-
You lost me there a bit Errol?
They are saying the 2:1 ratio speedo does not work which does seem to be the intelligent vote. If not the popular vote on all the info I have found. (also linked)
It seems by some stroke of luck as I said I got the 2240/60 speedo which seems to be the right one, Maybe these are the ones that Steve suggested dried up?
LOL Jonesy, I like the look of the XJ tacho, would that work on the XS?
-
Mate, I've got a feeling the XJ tacho is cable driven........been nearly 20 years since I had that bike. so memory is a bit vague
-
Hey Bretto.
have you deen these?

They suit the look you're after...I think.

Hey Eddy, I did see them but the tacho is cable driven. Also the seller states the speedo is "140km SPEEDO 60km = 1400rpm" which I think should read 1400rpm@60kmh (which I believe is the correct one for the XS) but then goes on to say it is 2:1 which I think is a contradiction?
-
Hey BrettS there is a way to check after your install of your new speedo, if it is giving you the correct info.
I have a formula here to show the proper Mph, based on engine Rpm DRIVEN tire diameter and the final drive ratio, if the bike is in a 1:1 ratio gear (as in 5th gear).
MPH = (Tire diameter in inches X Engine Rpm) divided by (336 X Final drive gear ratio).
For example my ford truck has 28 inch diameter tires and I wish to know how fast I am going at 2500 Rpm. I have a C6 tranny that is 1:1 ratio in drive and my final drive ratio is 3.25:1
MPH = (28X2500) divided by (336X3.25)
MPH = 70,000 divided by 1092
MPH = 64.102
So that is only a check after you install the speedo to see what speed you are doing. Note that tire diameter is off the driven or rear wheel only. Your speedo will be driven on the front wheel, so that tire diameter is not in play. It should work on any bike that has speedo issues.
My math may not be correct, but using the formula you should be able to see how much ground you are covering converted to MPH and then relate that to your speedo results.
Good luck with your swap!
-
Thanks Ras, don't have RPM at the moment ;)
I took the bike for a quick run today with the misses sitting on 100kmh so I could check the speedo and it come up trumps, spot on.
So for future reference this one was stated as, gear ratio 1400RPM @ 60KMPH or 2240RPM @ 100Kph. It is also noted that the speedo has a little sticker on it that states K=1,4
-
I've played about with various wheels in various bikes over the years... What seems to be common about speedo drives is that most manufacturers stick with the same external parts and modify the internals to suit the requirements of a particular bike...
So... What I always do is make sure that I buy the speedo drive to suit the wheel and then alter bearings/spacers to suit the axle and forks... This often means boring out the speedo drive to suit the axle dia, but it makes sure that everything fits as it should...
Hope that helps
