Hello all, I dropped my R65 the other day and the speedometer/odometer got bent but still worked for about three weeks afterwards. Yesterday I took the cover off and started it up. The odometer was stuck between 75999 and 76000 (KM). But the speedometer works perfectly. Has anyone had experience with this? What are some common ways to troubleshoot? Thanks.

Wait for Wirespokes to reply. He actually repairs these wayward instruments or can give you an idea for a DIY repair.
-
Great, I will. Thanks.

First off, to answer another question you had about the right side cylinder base oil seep - no - dropping the bike on the other side didn't cause that to happen. Especially having dropped it on the other side would have affected the left side, not the right.
As for the speedo - it's possible the drop helped dislodge a certain pot metal gear that tends to come loose anyway. The gear commonly looses its grip on its shaft and spins freely and slides to the side causing all sorts of issues. I frankly consider the odometer issue to be the most common failure on these bikes - from 1974 to 1995.
Repairing these things isn't an easy job, and made more difficult on the R65 by the crimped-on bezel. Once inside, it's a gear between the odometer and trip meter, which requires the total dismantling of the gauge - needle, face, and everything else - to access.
Some guys have JB Welded the gear with success. I've also repaired guages that were JB Welded and didn't stick. If you do attempt that fix, be sure to get the surfaces very clean. If you're careful, you may be able to JBWeld it without dismantling the mechanism.
Good luck! And let us know how it works out.

I had that speedo problem on my BMW car. As wirespokes noted, there is a gear that is something of a press fit into position onto it's shaft. With a bit of careful disassembly I was able to slide the gear aside, slightly "out of round" the shaft with a hammer blow, slide/tap the gear into proper position, and reassemble. Works like a champ.
Cheers,
Carl

Since your bike is non-standard, why not consider an electronic speedo? google trailtech.
They are not too expensive and will improve the look no end. Plenty of people here have done it.
Mine is not a trailtech, but you get the idea.

wirespokes, thanks for settling that argument between me and the previous owner. He hasn't talked to me since I suggested that the leak was on the bike before I purchased it. Kept talking to me about his "solid reputation" but I think his reputation as a doctor might not come into play with his reputation as a BMW R65 owner! I have to look at a breakdown of what's in the speedometer. The wire used to come loose on my norton all the time and I just had to tighten it down, but this sounds more complicated. If it was something beyond my ability, how much labor would be involved in paying someone to do it?
How do you uncrimp a bezel?
Steve, I like the electric tach on your bike, but I don't think it would look good on mine. Mine is like a caveman bike or something. I especially like the colored buttons. Which one shoots missiles?
-
wirespokes, could you guide me to the potential trouble spots on the diagram?
-
If you have an '82 model year bike, that is the wrong diagram, the one you have posted, is for the monoshock bikes .
-
Why do you say it's for the monoshocks, Bob? Those look like twin shock gauges to me.
I'm curious where that diagram came from since it appears the bezel is available. I want to get some! Those are one of the things I have a difficult time sourcing.
As for fixing the gauge - as a reference, I'm one of the cheapest guys around by a long shot and I charge $95 to service an R65 speedometer. I fix the odometer problem as part of the service. it's kind of a big job and not easily described, though there are write-ups on the web.
It seems to me the previous owner may have some issues. ;)
-
sorry, i changed the picture, bob was right, I'm sure.

Interesting that part number 10 (bezel) isn't listed in your parts list, but is on the MAX parts fiche.
As far as I know, the monoshock bikes have entirely different gauges - they're enclosed in a plastic pod, and the gauges aren't crimped into cans like the twin shocks.
The diagram you posted is for the earlier twin shock models.
-
Does anyone have a link to the right gage diagram for a 1982? I entered my VIN 6315719 into the realoem page and it came up as 09/81. Does that mean it's not a 1982?
-
The date of manufacture is not necessarily the model year of ther bike .
My '81 R65 was manufactured in 09/80 .
Seems like when our bikes were produced, September was the beginning manufacture for the next model years bikes .
-
Mines the same. It's 79 model registered in 79 but built in 78.
The factory started manufacturing the new model year after the summer break.
-
I've super-glued them back together successfully. Just be careful of creating a lump at the union.
-
i just want to visualize what i'm getting into before I break down the speedometer.

This article is for an R100GS but does show the technique to remove the crimped-in-place bezel.

Good luck. ::) And check for a PM to you.

Could you post this link in the FAQ/Procedures section, it's got some great info and won't get too 'buried' in there, like it would here .

I can do that. [smiley=thumbup.gif]

wow fixing a speedometer costs minimum 150 euros here and a 3-4 week wait. Wirespokes, in your opinion, is this something a novice can do? If I take it apart, and get stuck, can I take pictures of the pieces and have you walk me through it? what is the trick to fixing it? Is the trick just making the two gears stick? If I mess it up, can I just send it to you in pieces to fix? What is your turn around time?
-
That's a lot more than I charge! A LOT more. And I get concerned when it's not returned in a week! ;D
Sometimes it's taken three or four weeks and I feel rotten about it.
That's a tough question whether a novice could do this or not. There are skills and tools needed for the job that not everyone has. I've been opening up things my whole life, and the first ones didn't always fare so well. But with each failure or mistake, I learned. So I guess it depends on your mechanical aptitude and patience. If you're a very patient kind of person and enjoys (or can handle) working on small things and making, what seems like, very little progress, then you probably can do it.
Sometimes the simplest things can take quite a while to do right. You'd think removing a bezel is simple as just opening the crimp. Well, yeah, unless you want to re-use it and have it look like it's never been off. :)
There are instructions on the net in various places, and not difficult to find. And yes, the problem with the odometers tends to be a certain pot-metal gear that slips on the shaft. Guys have reported success in carefully JB Welding the gear to the shaft. Sometimes that hasn't worked, but may have been because the surfaces weren't totally clean of oil or not given enough 'tooth'. I do a fix that fixes the gear solidly in place and definitely prevents any unwanted movement.
Sure - you could send it to me! In pieces or whole. It doesn't sound like it needs any machine shop work (shafts, bushings, etc) so count on a week, maybe less.
