speedo help again, GSXR swap?

Hi guys I need some help. Last week I posted my speedo problem and it got deleted. My question is how to trouble shoot a broken speedo. Ground is good and im getting 12v. What should the last wire read? My second question is can I get rid of it all togather and use a gsxr speedo pick up AND display. I know it has been done but cant find any info. Im sick of not having one.

See here: http://people.tamu.edu/%7Ejmh7526/Sv650%20Portal/Write-Ups%20Page/SV%20Speedo%20Healer.htm

I did it myself. Pics here (text in Danish though): http://www.runes-mc.dk/artikel.asp?ArtikelId=12

I did that mod too. My calibration is -67.1% though, GPS verified.

There are plenty of site ( the ones above are very good) to hook up the speedo sensor and the speedo healer. It is fairly easy. The other part of your question, are you trying to use a GSXR guage package? I know that some people have done it, but I haven't seen any good posts on how to rewire the guages with more resistors or something. Hooking into your own display is easily explained in the speedo healer manual.

Has anyone done this to a 99-01. Forgot to mention that mine is a 01.

There's no need for the carbed bike (if you have stock wheels), you can just fit the speedo drive to the rear axle. Very simple mod, you just grind down the brake hanger and replace the spacer between the brake hanger and the wheel with the speedo drive. I've got a writeup for the job, if you want it drop me a PM with your email address.

I finally got her working. Turns out the rotor was not tight in the wheel hub and it was spinning. I glued the rotor to the hub and it works! I still want to get some info on the gsxr speedo swap. Who has done it.

i think i miss-wired the speedo sensor when putting it back together as it doesn't work now. (put speedo sensor on rear wheel due to GSXR front end swap).

so i believe you have to get the wires right (i thought they were 3 signal lines and the order didn't matter... now i suspect there's a signal wire, a ground, and a 12V line)

I cant keep my rotor from spinning. I tryed some glue but it didnt hold. Any tips? Still no info on the gsxr speedo?

i'm trying to jam in some rubber washers for some friction. :wink:

I'm still troubleshooting mine as well :) Though a mate is planning to make up a lil' billet spacer, which would be nice.

I'm not wanting to glue it, that's an easy fix but I'd need a spare rotor for each wheel, so instead I'm either going to nab one of those spacers, or build up a little castellation with JB Weld or similiar. The rubber washer worked fine for a few hundred miles then got itself pulled into the speedo drive.

So it wasn't miswiring that was keeping my speedo from working, it was a the physical sensor.

I had one washer in between the bearings of the rear wheel and the speedo rotor (that little metal/plastic sleeve with the 4 prongs). I had shaved off 2mm from the rotor as per instructions in a write-up, but I wuoldn't reccomend doing that unless you think you need to.

I ended up smushing in 2 rather thick rubber washers that I cut to fit over the bearings. one side of the rubber washer touches ONLY the bearings of the wheel, the other side is pressed into by the speedo rotor's 4 prongs.

so far i've only been back and forth to work a few times, but it has been working great. not sure about the longevity of this fix, but for now it works great.

also haven't calibrated it yet, but from what I hear from others, it shoud be about right.

P.S.
my brother (khskenny) just press fit his speedo rotor into his rear wheel and it works great. he didn't shave antyhing off the rotor.

Always good to know... One of the SV650.org guys just tried that and broke off a lug :) So that's why I suggested shaving off a little, but only enough to fit- did you take 2mm off each prong?

I've found rubber washers tend over time to get snarled up into the sensor, but if might just be that I've not found hte perfect size yet.

i took 2mm off the side of the rotor away from the wheel. but maybe you need that to leave room for the springy rubber washers. i definetly packed in the washers... thigntening down the rear axle nut really squished the rotor into the washers. hopefully it's enough pressure to keep things in place, but not enough to make the washers break.

Ah, that works does it? I was worried that that would push the rotor into the sensor too much and prevent it from turning. Hmm, good news, thankls for that!

If you guy?s are interested, I'm working on a different way to mount the Speedo. I should have the bike running this weekend so I'll let you know how it goes. I?m sure I have a few unexpected bugs to work out but, it shouldn?t be too difficult.

The total cost is ~$50 and the only down side is you?ll have to clip your stock Speedo cable (so you can use the connector). Although, it shouldn?t be a problem to switch it back if you want.

Here's a Pic

Let me know what you think

Sorry, I'll work on the size and repost WTF?

Here you go. I guess you have to URL the image and not the thumb. What a monkey!

Well my rotor broke, after the glue broke lose, so I need to try somthing else. I like the idea of the gsxr sensor, but know one has posted if it can be done on a 99-01. I am also curious about the newest idea (last post) Let us know how it works.

I also thought about drilling and tapping the output shaft but, just could'nt bring myself to do it. Changing the spacer on the rear wheel seems like you're headed for chain alignment issues?.

This solution should work very nice. I hope to test ride on Saturday so I'll let you know how it's going.

I think the alignment will be OK. you subtract away the extra girth you gain with the speedo/spacer swap by shaving down the brake hanger, then add in some washers to the brake caliper mounting bolts to add back there what you subtracted from the hanger. It's not as bad as it sounds. and in theory, the wheel is in the same place, as is the rear caliper.

Sorry, I missed the part about shaving the hanger and adding spacers. You're right. That should put the wheel back in alignment.

Definately interested in the alternative though... Watch this space :)

Anyone see this. Almost as good as the gsxr speedo. Saw it on sv650.org

Jimsv650s, did you every try it out? How did it work? Do you have a writeup availale? Thanks!

Just sent Youngkow the new version of the writeup...

I put up a seperate post regarding the rotor fitting. I couldn't get a good result using rubber washers, and I don't like the glue solution, so I've used chemical metal to build a little castellation into the rear wheel hub just like on the front wheel. I think it's a pretty elegant solution- it's reversible, durable, and makes fitting and removing wheels very straightforward. It's proved durable so far, the bike goes to the dyno soon so I'll see how it holds up to that abuse. Should be fine I think.

sweet. what is "chemical metal". how durable do you think it is, and how tightly does it bind to the wheel? where can I get some?

so far my double, thick stack of rubber washers is holding strong after a few hundered miles. Got it up to 110 and it still held up. i'll bring the bike to the track in 2 weeks and see what extended high speed does. although the real test is probably a long highway ride in the rain, or maybe some long dirt roads.

Northwind, Thank you! :bow:

yellow650, I think he meant something like JB weld. I think JBweld would work great in this situation.

Like J-B Stik or similiar, it;s a metal reinforced putty, heat and chemical resistant too. I can't actualy remember the name of the product I used :oops: but it's really effective. It's nice and easy to work and you can even tap threads into it (though it's not very good at that) It's very sticky, but it remains to be seen how well it'll last.

I got a bit p***** off playing with rubber washers :) I like the simplicity of this too, it's harder to set up but easier in the long run I think, and it won't freak mechanics out too much when they're doing my tyres...

Jimsv650s, did you every try it out? How did it work? Do you have a writeup availale? Thanks!

Yes. I did try it out. No problems at all. I'm working on the write up and plan on posting this weekend. I'm going to submit as a "tips and tricks" I'll let everyone know when it's up and running.

The speedo is dead on with the 70 series tire (verified by using a GPS).

Also, I'm working on a kit that would include the bracket and peices you need to mount the magnets. I might also offer soldering services for those who need it depending on the demand

well.. the rubber washer method DOES NOT WORK!!

Worked for a week or so, but i took it to the track and the whole speedo pickup unit is TOAST!!

Here's what I learned: You do NOT want to put ANY pressure on the inside spinning drive! It will work great for a while, but eventually the soft material will melt under the intense friction and heat and will meld with the outer sensor.

I had to pick out the inner drive and then replaced the outer senser (which is just a rear-axle spacer now).

Need a new speedo sensor. How's the JB weld fix going?? that won't put pressure on the spinning drive, but i'm worried that the JB weld will come off and then rip apart the bearings.

Chemical Metal's working fantastic... Set up my spare wheel with it at the weekend, what I've found is that it's not worth trying to keep it off the wheel, since it's a piece of cake to get the stuff out anyway when changing bearings. 500 miles in on the old wheel and it's basically as new. I did lose another tooth off the speedo rotor but I think I probably dinged it fitting the wheel rather than it being anything to do with the mod.

I wouldn't worry about getting bits into your bearings- or at least, not with the ones I've got in mine, since they don't have an open race on the outside. I'd say it presents basically no risk at all. Even if the stuff breaks up in the worst possible way there's plenty of easier exits for it than into the bearing. But bear in mind that i work in a bank, not a garage :)

i guess that's my next step after i get a new speedo pickup. any more info on where to get the chemical metal, or the brand name? Is the JB-stick the same thing??

do you have any pics of the chemical metal on the wheel so I can get an idea of what to do?

I'm still amazed at how the inner rotor just MELTED in the sensor. pretty weird material.. seems like some sort of platic infused with some magnetic material. unforunately its very brittle as well as melty.

I guess i'll stick on a BC800 bicycle computer in the mean time as a speedo. although maybe this will make me get a racing gauge cluster or a GPS.

Should be able to arrange pics, I've got a wheel with it installed in the garage. JB-Stik should be very similiar, the stuff I used is Evo-Stik Chemical Metal but there's half a dozen similiar products available in the car-stuff place I go to. I think JB Weld would be too thin

JB stick works great!!

thanks for the tip.
