Is it true that it is not so stable at the midpoints??? I read where you need to jack it all the way up to get it completely stable.
Yes, it is most stable at the highest point.
No concern starting the bike on the jack and running through all the gears up and down multiple times while servicing.
The only time I tied it down was when I removed the front forks and the swing arm and trans.
and 1 other question...why doesn't anybody suggest the Pitbull...it lifts 7in higher than the J&S?
Using my roll around "scooter chair, the J&S height is perfect, have never needed it to be higher. Any higher and I would want it high enough to stand up and work.
