Update on Sticky Speedo

So, I've done some experimenting on my own and discovered some interesting stuff.

In July, I took a ride out to Colorado. Rode across Kansas in 100+ degree heat. While in Colorado, rode at elevation with temps below 60. On both occasions, I was able to get the speedo to stick and also to fix it.

Bear with me, because the rest of this sounds abso-freakin-nuts...

I bought myself $1.69 worth of white Scotch Adhesive Putty. Yeah, the stuff you put posters on the wall with. I pressed out a circle of putty about the diameter of a quarter. I then placed said putty circle over the speedo dial so that it created a shadow over the little chrome bling piece that caps the speedo spindle. It fixed the problem for me every time.

Here's why I think it worked:

I only really had the problem when the sun was high in the sky. In July, at my latitude, time of day was between 11:45am and 2:45pm. If the speedo's chrome dome bling part (yep, that's the technical term) was left in full sun, the speedo stuck.

I think, between the glass cover on the whole face and that little chrome dome piece, it was lensing the sun's rays onto the speedo spindle making it swell up and stick. As long as I kept the damn thing in the shadow of the putty circle, it quit sticking.

I must be on to something because Triumph asked to switch out my speedo cluster for a new one and wanted me to send mine to them with the putty in place. Even had a guy from Triumph call and talk to me about it.

But, I did get a new speedo with zero miles on it. Was like getting a new bike, right??

Interesting. Now that I think back on it, this was pretty much the case with me as well. It only seemed to happen when the sun was high in the sky shining down on top of the speedo.

I even tried covering it up when I parked it for lunch, and when I got back it was fine. I think you may very well be onto something there. Now, if only Triumph does the right testing and finds that this is the problem, I figure they will be able to setup a fix in manufacturing pretty easily.

Fine... they can try that. I am not going to hold my breath on it though. I will keep the idea of the gear position and road speed sensors in mind, however.

My guess on that, if it were either of those sensors, is that it would be the road speed sensor, as it didn't seem to matter which gear I was in, or if the bike was even completely stopped and kill switch applied... the speedometer would be stuck at some value other than zero.
I agree - mine screws up in any gear when it takes the notion to get wacky or sticky which is currently often - It also screwed up when I got snowed on at MT Evans CO at 38degrees F so it isn't the heat, at least in my case. My dealer says he isn't getting any help with this and I reported my first experience with this three months ago. I currently have about 6K mi and now the speedo seldom works correctly.

As an outsider looking in, its easy to say they didn't do their jobs, but

I'm not talking about simulation, I know that they did a lot of road testing in the real world. With all the bikes that they were were riding and using for demos all over the world, barcelona and the like, I find it a bit odd the the problems were never noticed until people started buying them. Especially when there are posts here that say they had problems on the way home from the dealer. I can also go to any dealer today and buy another one with a bad speedo and no mention of problems. At that point the consumer is one with the speedo - STUCK!!

OK, but how many bikes have this problem? Certainly a good number, but I suspect that majority of the bikes don't. So, perhaps none of their test bikes exhibited this issue. Or maybe one did, which might cause them to believe it was just a bad component, not a design flaw.

Now they know it is an issue, which is why they asked for K12's speedometer, but even tho there are several birds on the showroom floor that have this problem, doesn't mean they know the cause. Sounds like they are working on it now, but understandably, it might take some time to figure out and when they do, they'll work with the supplier to engineer a fix (read more time) and then that new component will go into manufacturing - new drawings, QA tests, manufacturing procedures (read more time) and then that component will be sent to distribution centers (more time).

Its just the way it is.

This is bloody annoying to me, because I know that I will have to be damned sure every single bit of dirt, dust, and grit is out of that area when it comes time to check/fill the oil.
I am with you on this as with all of your posts. What were they thinking, putting the dipstick at a low point. It needs some sort of a standpipe because I won't even check the oil without washing or blowing out the area with a compressor. I bought the chrome logo dipstick just before I took a Colorado trip and it turned out to have a pit in the o-ring and blew oil down the side of the bike but I still didn't pull the plug because of the sand and grit around it.

Heck, this is the dealership that, when going over the bike with me, told me that it doesn't have auto-canceling turn signals.

Anyway, the kid that worked on my bike is actually a good guy, and knows his stuff. He pulled the unit apart, completely disassembled as far as he could what was there, noted that there was a ton of dielectric grease in the connections between the speedo and the cabling, and that a couple of the connections appeared to not be fully connected... sort of half-way into their sockets. This is a good thing, I figure, as it may actually have been the problem.

I guess I will just have to wait and see.
I feel your pain, I really like the bike but why all of the deception? They tell you they have never heard of the problem-Well They have heard it from me! As with the coolant leakage. Have you experienced that one? They claim they have a cure for the coolant but nothing on the speedo yet, but they are still selling the bikes to unsuspecting clients. This is not a noble business practice. I hate to see them drive another bird into extinction but...... I have never seen deception followed by long-term success. Only honesty and integrity can do that for them!! Triumph needs to come clean on this one!!!

I understand - You work for John Bloor, I thought he was a more noble man than that. Long term success is not acheived through deception- only honesty and integrity can do that. What about the coolant leak?? Every T-bird that I know of has the problem. They will fix it, but only after you buy the bike. If I wanted greed, deception and no assurance of quality I would have bought a H-D. I suppose you're ok with driving a runaway Toyota! Good day!

sticky speedo

engage - Dude- What planet are you from... what if the engines were blowing up and they were still selling them, would you say "don't worry, it's only happening to a small percent and if they ever figure it out, they will fix it - so go ahead and buy the bike anyway... The odds may be in your favor. NOT A NOBLE BUSINESS PRACTICE. COME CLEAN, QUIT HIDING AND RECALL!!!!!!!!!!!!!!!
