You mean 22 (not 21).

Quite certain you can get the All Balls products in your countries as well. You can find a dealer by first searching the distributor list for your country. http://www.allballsracing.com/index.php/dealerlocator

No I mean 21, 22 is labelled as an O-ring.

I didn't know all-balls did them. Considering I've changed them once in 10 years I don't mind buying genuine as I know they'll last as long again.

[Andre]

You are right Hooli. I had looked at page 70 for K2, 3, and 4. For K5 on page 71 the numbering is different.

[Hooli]

I didn't even notice I was looking at K5 forks, it looked the same as my K2s.

[Buddynq]

Mine is K7 so assuming nothing has changed since K5

[Andre]

Checked here http://www.robinsonsfoundry.co.uk/shop/online-store/suzuki-parts-finder/gsx/gsx1400/k2-k3-k4-k5-k6-k7-2002-2007.htm#!gsx1400frontforksk6k7 The bushings are the same for all years! But at least the spacers are different between K2,3,4 and K6,7. Robinsons is one of several good sources to obtain part-numbers. Their prices are not that good though. Most of the times I get original parts in Germany for a lot less.

I'm pretty sure the only time the forks changed was between K4 & K5, like most things on these bikes really.

I don't suppose anyone has a picture of the "fork tool" that's been mentioned here ?
I'm about to pull out the forks in my 2001 1400, and replace everything.

Thanks,
Peter

Thanks mate.

Thanks Gsxbarmy for a very detail notes. 

There was also a youtube video uploaded by a Japanese owner may show some process for reference:
https://www.youtube.com/watch?v=3RJJGPJfOGA

however I have no knowledge to verify is it showing the correct / full process...

at 9:10 the dude puts a copper ring in the oil stop, I just saw this after assembling my own front fork and I didn't put it there. I followed this diagram: https://www.motorcyclespareparts.eu/en/suzuki-parts/2002-gsx1400-motorcycles/front-fork-damper and I don't see the ring in there. I have 2 spare rings in my gasket/bushes set I bought of ebay (all balls racing) and since the set is for more motorcycles I thought they where spare.  I also didn't see these rings when disassembling the fork.

[Andre]

Didn't you mean 8:50 to 9:10? That would be the copper gasket (#6 in the drawing in your link) for the bolt. Should go there. Maybe it still clings to the lower tubes?

Sorry for the confusion, I mean at 8:10

@Donatello

I looked into the service manual, Robinsons (all models), 2 German 14 forums, and another Japanese YT video (see below) as well as this forum. Neither shows/mentions these mysterious copper rings. I am quite certain I had these rings left over as well.

I used a cut broom handle shaved to a point..
It worked very well..
I too replaced the Bushes but at the lowly mileage of 32k miles, they looked like new with no discoloration or evidence of wear.
I did fit a progressive spring kit from Hagon if I remember correctly..

Be aware that in this kit they DO NOT provide enough oil!!
I ended up using Rock Oil 7.5

By the way Thanks originally to Andre this table for fork oil viscosity is a real eye opener..
As Andre once said, "Don't go off what the can says" (or words to that effect)..
