Guys I just noticed the other day that my speedo and tacho ('78) are not the same size. Is this normal, or has some previous owner slipped in an XS650 ring-in?

P.S. anyone know where I can get my speedo checked out? 60 km/hr at 5000 rpm on 17/42 gearing can't be right.

GPS device for speed check, maybe - or have somebody follow you and honk at certain speeds??

Get someone on a modern bike to ride beside at whatever speeds you are interested in and see what yours says...don't use a Kawa as from my experience they notoriously over read...for instrument maintenance try Lionel Otto Instruments, in Brisbane. (07) 3277 3888... SR  |

I havn't used or tried to contact them, but I have been told Adelaide Instument Services can calibrate speedos. Sorry but I don't have any contact details for them.

At 5000rpm you should have been doing 140kph ! So whats knackered the speedo or the taco?I've replaced/had rebuilt both on everyone of my SRs as they seem to eat them . Lucky for me my old boy has managed to open them & he's been able to make one out of two . Now I'm down to no spares (I've also noticed that they demise at around the 80k mark)Cheers Dave.

Having problems with your Speedo and Taco? Try a different swim suit and stay away from the Mexican food. ;D  |

THAT'S FUUUUUUUUNNY! But realize the coloquialisms are different in OZ than the US. For all you guys beneath the Equator, we call a speedometer just that, and a tachometer, a tach (tack). I've seen turn signals called "winkers" and "blinkies"......I guess we're a bit stuffy up here, or maybe lack imagination?
Language is fun.

Heh, heh.
The tacho appears fine. I have a GPS, and the bike is doing about 119km/hr when the needle is hovering at 5 grand. Unfortunately the speedo, by which I mean the speed measuring device attached to my motorcycle, NOT the famous Australian swimsuit used for smuggling a certain native bird, has slowly got slower and slower to where it now reads only 60 km/hr.
I'm wondering if anyone knows whether the speedo drive in the wheel can slip? The reason I ask this is that the self cancelling indicators, which work off a reed switch which senses directly off the cable drive plus some sort of timing thing at higher speeds, are gradually taking longer and longer to cancel at highway speeds. As this sensing thing is really taking place right at where the cable enters the instrument, before the erroneous indication of speed, I'm wondering whether its actually the cable turning ever slower?
By the way, I refer to my GPS as the lie detector. It has been my experience that many a modern sports bike rider has report a highway speed between 10 and 15 km/hr faster than I'm getting riding alongside him with my GPS.
When the guys all say they were sitting on 120 km/hr, and I'm riding in the bunch with my GPS showing 110, guess who I believe?
I put it down to most modern sportsbikes driving the speedo off the countershaft sprocket these days, and with the mega ponies they are transmitting, there is no accounting for wheel spin, etc.

Hi Mick,
I have had the same problem, it was caused by oil from me over lubricating the cable getting
inside the gauge.
The solution was to remove the cable from the gauge and use cotton buds to soak up as
much oil from inside the gauge as I could and dry the top few inches of the cable with
tissues. It did not come good immediately but after a couple of K's of riding it came did,
and has been working fine since.
Hope this helps.
Cheers, Mike.

Mine just totally pooped itself & started going around & around & the taco's needle just dropped off so maybe I should have just stuck it in the microwave!(tucker fu**ker) I've seen the word "seppo" used a couple of time on the forum(I bet you fellow American SR brothers would not be too impressed if you knew where that one came from!)Personally I wouldn't use it ,cheers Dave.

I'm guessing mikec has the answer for a lot of speedometer and tach failures. A guy who repairs antique clocks once told me the main reason they stopped running was they were over-oiled by the owners.
As for "seppo," well, we're a pretty thick-skinned bunch. I don't think anyone is going to take much offense. Anyway, there's plenty of colorful language slips in around here. Just the other day someone used "beaver" in a post in a way that made me think it might mean something besides what G-man and I up here in the north woods think it is.
Just the same, if I were in a biker bar here I'd probably use seppo before I talked too much about "my taco." Might be misunderstood.

Thanks for the advice guys, I'll check the oil situation, etc.
As for the term "seppo" I won't use it, where I was brought up it was a mildly derogatory term. Not unless you call me a "F@#$ing Skippy", a derogatory term used by Mediterranean Australians about Anglo Australians in my neck of the woods.
As for beaver, I had a truly hilarious moment at a contractor meeting at work a while ago.
A fairly conservative guy who worked for the contractors had asked me the day before whether I had heard the term "beaver". His boss had used it, and the poor guy had to admit he had never heard it used that way before and suffered great embarrassment as all his work mates ribbed him unmercifully.
Over here "beavering away" means toiling industriously. So next day we have this big planning meeting, and the naive guy was a no show. So I ask, straight faced, hey where's the little beaver today?
His boss, ex bikie and renowned hardcase, looked at me and disssolved into uncontrollable laughter, tears rolling down his face. Only me and him in on the joke, the entire meet a shambles before it even started, and a half dozen metallurgists totally mystfied as to what is going on.
Language is a truly wonderful and powerful thing. Use it only for Good, grasshoper.
Mick
