Someone will chime in with confirmation but recall that people have swapped KLX front suspension onto KLR so the reverse will be doable. I'm not recalling if the steering stem and triple tree was a direct swap which is what you really need to know. If memory serves there was discussion in this group around that subject but perhaps the site upgrade has made the old stuff in accessible?
There were some KLX people on Yahoo so may be able to check there. Too bad there was damage to a KLX as KLR are common place but KLX rare.
Regardless, please let us know any specifics you discover and perhaps someone will remember for the next person.
