Kudos to Oengus and Allen; good sleuthing gentlemen!
As with the LXT 400, the Honda, NX250 engine also has a countershaft with 11 splines.
This is further evidence the bottom end of the LXT 400 engine might be patterned after the NX250 engine.
For LXT 400, countershaft sprocket information, check the following thread.
