Ok when I first got the bike I bought V-Trec levers.
The brake is ok but after a few posts from the other XR forum a couple of issues were found and I had these as well
The first is that the small post underneath does not align correctly with the microswitches
but more importantly the clutch lever does not sit back correctly and pulls the cable in the wrong way
Damage will eventually occur
So I looked for another lever and found that the ABM levers work as per Hornig video

Loads of adjustment and look really well made
