Well was about 4 hours or so. But man they have it jammed in by the shock and you have to disassemble the unit from the bracket and take it all out separate. But that is after jacking the bike up and taking apart the push rod and shock and rocker. But its mostly back together. I just got plain hot with 100 heat index and only have tank and seat to put on. High point was the tank only has about a gallon of gas in it. That has to be a first.
