Instructions worthless, go on youtube. Install went ok, spent most of the time insulating and routing hydraulic line around exhaust. Sounds like a few people had trouble with line burning on exhaust on the 400ex. I ran mine thru 5/15 fuel line ,then wrapped in silver heat insulation, like you would use on the floor of a car. Put 50 miles on today, no problems. My old clutch was very hard to pull. I had wrist surgery and could only pull the clutch a few times. Now I can pull it with 1 finger, works great.
