GS1100GK fork specs
- Thread starter gs58
- Start date
This is what i use. It has a 17mm nut welded on the end.
Is 17mm the outside measurement of the nut (across the flats)?
Because we tried to use a tool with a 19mm nut on Larry's 41mm GK forks, and it seemed to be too small. It works great on 37mm forks, but seemed to be too small for the 41mm forks.
I am officially confustimicated.

Ok here is the tool I got from work when they shut down.
OK the tip itself mounts on the 3/8" t-handle. The tip is Suzuki part # 09940-34581 and there's one on ebay right now for $25 item # 140521663538
It seems to measure around 18, 22, and 24mm across flats and I had the 22mm installed outwards but I dont remember if my 1982 GKZ was the last thing I used it on. (but I'm pretty sure it was)

One could purchase a 3/8" thandle or manufacture one, then take a large 3/8" socket (larger than 22mm od) then grind flats on the outside circumference of it.I was forced to do this on a Bruteforce 650 front diff the other day when i needed a 35mm hex id and a 41 or so mm hex od.

I have a list of fork tube diameters and other info going in the "need some
help compiling a database" thread. Shane (kiwiGS) offered it up and I think Dan found it originally. But there are some I'm not sure about on the list. They listed one of the GK models as having 37mm tubes like the other big GSes but most of the GK model years as having 41mm. A bit odd.

GK damper rod recess star measurements
GK damper rod recess star measurements
As you know, there are two 12 point "star" patterns in the end of the damper rod (inner cylinder) for our for forks. A 14mm nut fits snugly inside the inner star pattern without any wiggle. A 17mm nut fits within the outer star (like others have mentioned). The machine shop gave me a 5/8" nut to fit into the outer star. btw - 16mm is almost the same size. Those MIGHT work but they don't fit that outer star snugly. They move some before getting wedged in so I wouldn't recommend them.
I was trying to get the machine shop to attach a 14mm jam nut (glued/braised) onto a 17mm jam nut and then attach those to a threaded or solid rod. Using the damper rod as a pattern in order to get the offset correct. All I got was a blank stare..... I still think it could be done. However I can't find a 17mm nut (jam or regular) in greater Cedar Rapids - So I'm just going to use 14mm nuts and a threaded rod. Hope this helps.

Actually just placed a 18mm socket over my tbar and must be that size for GS1000 and katana.
