I just put a small piece of 1/4 in plywood about a foot square ,on my floor jack ,slide it just back of where your feet go and up it goes .Just don't go to high if the center stand comes off the floor it will tip .When the back wheel hits the floor you are just about there . I really didn't like where the jack was in that picture
I think that would be to tippy . If I need it higher I will tie it to my over head
chain winch in the ceiling just so that it can't tip .That is the big worry here
is to not tip it off the jack .
