no need to use the cups as long as you can somehow secure the magnets on the rotor. I only used epoxy glue and they are stuck fine. I was using just electrical tape for a couple of weeks before gluing them and they didn't come off even at 120mph.

Is there any specific purpose of the cups from Lee Valley Hardware beyond just to hold the magnets?

I found another set of magnets that fit neatly on stepped portion of the rotor hole and I don't need to use the cups unless they serve anther purpose.

Out of curiosity, where did you find the magnets, and how do you plan to secure them?

I purchased the magnets from a guy from work. I will post photos when I get it all together.

I may be able to get them for you guys if anyone else is interested.

I thought I read somewhere that the cups were supposed to make the magnets stronger, but I'm not sure.

Yep, they do

Finally got around to mounting the speedo sensor on my fork swap. I used the cherry one everybody else using. I mounted it so it faces the space between the friction surface and the carrier. It picks up the rotor buttons as they pass just fine with no magnets. Pleasant surprise. Just throwing it out there in case anybody wondered.

I got a question regarding the sensor needed and magnets and referred it to this thread.
For those of you with 9 spokes who also want to correct the factory mis-calibration check out 12oclock labs' calibrator. I got one and it works great.
See here: speedo DRD
I figured I may as well create an endless loop.

Can you show a picture of where you mounted the sensor? Is your speedo accurate with the setup? Thx

Works great. Totally glitch free just like OEM. The only issue I had was that my 03 only needs to be triggered 4 times per rotation. This triggers 8 times since there are 8 buttons. My speedo healer took care of that.

Thanks for the picture.

But a healer is require properly to run your setup. Guess sensor with 8 magnets are more cost effective.

Healer is only required for 03 and 04. The 05+ don't need one.

So I've read through the thread and still haven't been able to find a clear speedo solution for the 08-09 gsxr front end on my 04 SV650s. I assume the easiest route is the hall effect sensor because it is the most popular. Just wire it in, make a bracket and go. My main concern arises with the magnets. I have 12 button 08-09 wheels. Just to confirm, should I use 4 magnets spaced 90 degrees apart? And if so, will I need a speedo healer as well?

 

[sidepipe79]

4 Magnets, spaced 90degrees apart, no healer needed.

 

[AZ-Ben]

Thank you for the folks contributing to this thread, I just ordered the hall effect sensor and magnets for my 07gsxr600 front end I am swapping onto my 2006 sv650s.

Hey SVRiders!!

It's been a while, and I did say that I'd come back and post when I got things running.

I did the front end swap and I kept my stock gauges and put on a GSXR 600 front end. (year isn't important.)
I did this to keep it looking somewhat stock and to keep from having to buy a new speedo.
I will eventually upgrade, but it wasn't in the cards when I did the mod.

The sensor I used was from a KTM 610 that I found for sale on eBay.
The sensor was pretty low profile and sealed from water and grime.
I have no idea if other sensors from KTM would work, I just know that this one did and I only know that because I tried it and it worked.
(I mostly based this off of the fact that it had the same number of wires. Trial and error works sometimes!!)

This is a link to the first video where I show the connection and it working.

Here is a link to the second video where you see the bracket holding the sensor.

I've found it's relitivly accurate, but I haven't tested it against another vehicle and I have not tested with a GPS.
I'm just basing this on flow of traffic and my Butt Dyno.

I don't have a photobucket account so I can't post pics here.
If you want a link to my build on another site, just PM me.
(might take a while for me to respond as I don't drop in here as often as I'd like to.)

Thanks for looking, and to this site for providing the info that made the swap possible.

I have the 08/09 front end with the hall effect sensor from Jameco and rare earth magnets ala Home Depot. Four magnets are spaced 90 degrees apart. Right now it's running about 10+ mph lower than the actual speed measured on a GPS.

I will try flipping the magnets to see if there is any change, but does anyone have any other ideas here? Last resort, speedo healer.

 

[TeeRiver]

Yaozer, that's odd. The '07 SV speedo expects to see 8 pulses per wheel rev. 4 magnets, even if they are all working should read 50% low, not high.

I don't know what's going on with your setup, but you can monitor the Hall sensor by clipping the black lead of a voltmeter to battery (-), then the red voltmeter lead to the Pink wire going to the SV gauge. As you spin the front wheel, you should see the voltage drop down close to zero each time a magnet passes the pickup.

Edit: Maybe you mean 10+ MPH low? If you see 10MPH when expecting to 20MPH, then it makes sense. You will either need to use 8 magnets, or a speedohealer.

Yes, it is 10mph lower. If I add four more magnets, they will not be equally spaced apart bc there are only 12 rotor holes.

Just not sure why this is coming up.

 

[TeeRiver]

Half the magnets will report 50% low. 10mph instead of 20mph; 30mph instead of 60mph, etc...

If that's what you're seeing then you just need to decide if you want to fit 8 somehow, or use a speedohealer. If the speedo is not 50% low across the range then there is something wrong with sensor setup.

drinkbrew had good success making 8 magnets fit an odd spoke rotor this thread. See post# 38.

I have a 2003 SV650S with a 2003 GSXR front end. I'm assuming I need the Cherry Hall Effect Sensor, 4 magents, and then just build myself a bracket to mount the sensor. Then space the magents evenly apart so they pass through the magnetic field of the sensor. Would I need a speedo healer or is there a way around that? And would I need 8 magents or not? Thanks for all the help guys!

You need 4 magnets and a speedo healer is not required.

Check out my 02 GSXR Conversion link below to see how I mounted my magnets and sensor.
