Just bought the jack, took it home, ripped off the poorly attached Mastercraft Label. Put the GL1100 on it and took it to the top, locked it in the safety locks and it sits high enough for me to sit in a seat and work on the bike. Rocked it, rolled it around the garage. NO problem. But I did make slight modifications.
I cut up 2-2" x 6" lumber to have the bike sit on the lumber and this keeps the exhaust pipes from taking the weight of the bike. Also the second 2" x 6" is notched to fit between the arch way in the over night stand. I mount the bike on the jack with the main stand holding the bike up, then slide the cut wood into the stand so with both pieces of lumber in place the new jack holds the bike from the frame and not the motor, transmission, or aluminum parts.
At $89.99 + 15% taxes the jack is helpful, I still find I crawl around on the floor but visibility and access is easier. The safety hooks are great and that is what hold the bike up, not oil under squeeze. The included web tie down is OK, it keeps the jack and bike as a unit and as a unit can withstand some rocking. In removal of wheels I would have a buddy (wife) keep a hand on the bike just in case. This will take some getting used to since it sits uo fairly high. I have also tied the whole thing off to the sides of the garage and at that it is very stable.
Storing the jack seems OK, I leave the detachable handle in place. Another fine quality copied product from China. When I examined the whole thing I am still amazed that they can make it for that price, ship it to us, CTC makes its 35% and everyone is happy. Just wait until the Chinese figure it out, who will be our next cheap labour market maker.
As I tell my kids eat up, since there are starving people in China, now I tell them study hard since there are starving people in China and India who want your lifestyle, job, career. The jack is a good tool, just use common sense and use safety, since there is no margin of error, keep the floor clean and remember a lot of garage floors have a 1/4" run off to the foot so a loaded jack on wheels can roll.
