Brough my 2023 V85 TT Adventure home yesterday. I noticed the pickup for the ABS sensor was rubbing the sensor ring. I removed the screw and took out the pickup to see what's up and the pickup has been ground down where, in fact, it was contacting the sensor ring. I looked on the parts diagram for the bike and I see no shim/washer there, so I wonder what's up? I suppose an easy fix would be to shim the pickup with a washer, or file/grind down the pickup a tad more, but I wonder what is the problem to begin with?

Thanks for any comments.

Tim

I would not remove any metal from the pickup, a washer may be a good temporary fix till you can get it to the dealer.
 
If I was near the dealer I'd shoot on over, but path of least resistance...
Just curious what could be the problem. My guess is maybe they used the wrong pickup.

The manual might tell you what the gap should be. I would call the dealer and report the issue. Ask if you can contact the Regional Dealer Tech that helps out the techs at the dealership. Call the 800 #.
Call the dealer in Grand Rapids, their Euro Tech is supposed to be pretty good at that shop.
 
On a new bike (under warranty), both sensor and tone ring should be replaced since both have been rubbing against each other.
 
Update: Problem resolved (not necessarily solved). I'll either get praised or ridiculed for finding a solution myself. We'll see. The issue is, that my dealer is about 250 miles away and all that that entails.

I started taking things apart to have a look. Upon loosening the rear axle nut, the swing arm spread apart about 3mm - a lot more than I would have expected. This also indicates that the swingarm may have been under stress. When this gap opened, I was able to displace the brake caliper mount plate to the left providing a gap between the brake caliper and the sensor wheel/brake rotor - about the same gap I've seen on pictures of other bikes.

I removed the rear wheel and continued to fiddle and examine parts, but the only thing I could come up with was that either the caliper mount or the left wheel bushing were machined improperly. So I went down to my local big box hardware store and bought a 3/4" washer. I had to grind down the inside just a tad to fit on the axle. I fit the washer between the wheel bushing and the brake caliper mount, tightened the rear axle nut to specification and voila! Perfect.

You still need to get this to the dealer. Yes the washer is a temporary fix, but there is an assembly dimension issue that needs to be corrected under warranty.
