check the sensor on the rear wheel, the bolt may have loosened it worked for 2 rides so either it got loose and out of spec, or ,, kI have seen in one neighbors bike, he put the sensor too close and it wore the face off the sensor and of course it quit, maybe even a wire in the rear wheel area go t damaged, lets hope for a loose bolt

 

...also may have bent the tone ring

 

if the shop did the work, I'd also check to see if the axle bolt was loose/installed

 

I put a new rear tire on the '08 650 Exc yesterday and after on my 2nd ride the EBS came on. What did I do wrong to get this light to come on and how do I fix what I did wrong?

My money's on a bent ABS ring.

The rear ring is just hanging out in the breeze back there, very easy to inadvertantly bend, as opposed to the front ABS ring, which is sort of encased in a holder. I've had two GEN I Execs, for a total of 11 years, and EVERY time I had new tires put on -- I don't have the tools or inclination to do this myself -- I made a printout of the work to be done by the shops, which always included a warning note about being careful with that rear ring.

If you have a run-out gauge, or just a good eye, spin that back wheel, and watch for waviness in that ring. And if that's the case, unbolt it and then flatten it back out, the way it should be.

 

I got a refreshin beverage bet on a loose bolt! it ran twice with no failures no brown beverages accepted, green ones only in 40 oz size

 

I'll take that bet. Not sure when I'll be Florida again, though.

 

I didn't check the bolt yet but did spin the rear tire and measured the distance between the rotor and the sensor. I was getting between .032 and .028 on a full rotation of the wheel. I don't know what the distance should be, don't have a shop manual. Will check the bolt tomorrow after work and see if it is loose. Thanks for the help.
Also, need to change the title to ABS not EBS, but not sure if it can be done.

I don't have a Burgman 08 manual, but those figures are in spec for my ex-V-Strom, which uses the same part numbers for rear ABS.

The ABS tone ring should have FOUR bolts.

 

Had some time this morning before leaving, went out and checked the bolts on the sensor and the 3 of them were tight. Have not ridden the bike yet to see if the light has gone away from what I did last night. to the tone ring.

 

I dunnooooo my research shows 2 bolts on rear sensor, my 15 model only has 1 Ed's (The guy who ground his off) only has1

 

I think that there was 3 but could only get to 2 of them. I am guessing that there are 3. Saw some paint to the left of the sensor that matched the paint on the right bolt, so I am guessing that there was a bolt there. Could not get a wrench on what I thought was a bolt.

 

i'm out not having an 08; 650 i shuda not got started. wspollak i'll send you a check for 1 beer, can you wait to cash it till i get my income tax rebate

 

Sure, I’ll wait (heh heh).

 

The tone ring bolts to the rear wheel with four bolt. The sensor bolts to the final drive housing with a mounting bracket. Two bolts secure it to the bracket. One bolt and a locating pin secure the bracket to the housing.

Since the last thing you worked on was the rear wheel then the logical assumption is that the rear wheel sensor is the problem. Assuming that is so then the possibilities are the tone ring is bent, the gap between the tone ring and the sensor is to wide, the tip of the sensor is fouled, the sensor is loose, the sensor is malfunctioning, or the connection of the wire from the sensor to the control unit is loose.

Looks like you have checked for a bent tone ring and it seems to be OK.

Gap between the sensor and ring should be 0.3 to 1,5 MM. You measurements indicate you are within specs.

Check to see that the sensor does not wiggle due to it connection to the bracket being loose or the bracket connection to the drive housing being loose. If not then

Remove the sensor and clean the tip of any contamination that might be on it. Reattach it and test to see if the problem is fixed. If not then

Follow the wire from the sensor up to where it plugs into the wiring harness. That is up under the seat behind the 2 40 amp fuses. If you are lucky you will be able to reach the plug without having to remove the the left rear panel (the one with the gas filler door in it) but don't bet on it. Make sure the wire has not pulled out of the plug and that the plug is not corroded.

These were the steps I followed when I had a similar issue. My problem was that the wire had pulled out of the plug. I took the plug apart and reattached the wire to it then plugged it back up. That fixed my problem. I did have to remove the left rear side panel which is a pain as that is probably the most difficult piece of bodywork to remove and replace.

If all that is OK then you may have a bad rear ABS sensor. Either that or the problem is in the front sensor or the ABS control unit. Your going to have to get into some testing procedures that will require a multi meter and a service manual that details the procedures.

 

Have been busy the last couple of days, leaving at 7:30 and not getting home till around 10 that night. Finally had a chance to ride the 650 this morning after making the adjustments on the tone ring. The ABS light went off after a very short distance of riding. I want to thank all of the help with my problem from you.
