I would upgrade rear shock before messing with motor.
You need two manuals. One for klr600, and supplement for klr250.
Thanks- already started messing with the suspension, front & rear. I have a 130 lbs rider on it so not as much work needed as for a heavier rider. I also have both manuals & just figured I would reach out to this group for recommendations on things that work or didn't work.
I think I have found some good ideas, but keep them coming & I will give updates on what I feel worked best.
