I'm approaching 20,000 miles on my bike and have done nothing to the forks other than change the fork oil. They're getting a bit harsh on rough surfaces, so I'm thinking of taking them to a fork specialist to see if I can get some improvement in behavior when braking coming into a rough corner.

I'm considering having the work done locally by either Lindemann Engineering or Aftershocks. I have the 1997 Showa forks that come with no adjustments and you can't just buy a kit for them.

Any suggestions or experiences with getting forks reworked would be appreciated. (And no, I don't want to buy other forks for the bike.)

Hey Scott....I haven't checked you particular year I probably will after I post this......but I reckon if you are going to a specialist all is well there...just make sure that whoever looks at the forks
checks the damper tubes to be working properly and without stichion....if you need new ones it is going to be quite a wait and they are not stocked by DNA.......I also have reason to suspect this part on bikes with some miles........I also found who I think is a great fork specialst in Dan Kyle.....in cali. Although known for engines, a great fork resource....
you may want to talk to them also about your forks......

Good Luck....aloha retro.....

ps I had my forks revalved and new springs with ractetech parts....but I have also heard bad things about gold valves, although I have no direct knowledge of why people may not like them..I have heard some disparaging remarks from some fork specialists with no particular axe to grind or selling something else....so I am also trying to gather more info on that also.......

Lindeman does great work. PS: Get the adjustable 43mm forks & dump yours!!

only those with competing financial interest have anything negative to say about Race Tech gold valves.

now... talk about servicing forks? well... the only people i haven't heard something bad about (or seen with my own eyes) are pps, traxxion, and kyle

note that dan kyle can put ohlins internals in the showas.

Is that the non-adjustable showas he can do that to, or the adjustable ones also?

I'm beginning to think that the adjustable Showas on my S4 are never going to be capable of dealing with the high-frequency stuff, and the adjustments don't seem to effect that performance zone much. If I go softer, they just get wallowy.

I thought I had read somewhere that the Race Tech gold valves couldn't be used in the older non-adjustable Showa forks.

they fit cartridge forks, but not damping rod style forks, although they do have an emulator for damp kind.....gold valves I think should work from '93 on......

The non-adjustable forks which cannot be revalved are the marzocchi ones. they cannot be disassembled.

ohlins goodies i know work in adjustable showas. prolly fit in non-adj showas too. you'll need to ask dan kyle, who may truly know something baout his product.

no modern ducati forks are damper rod.

marzocchi forks are cartridge, but the cartridge is not designed to be removable or serviced.

Whoa... I know I've read this on here numerous times but this throws me for a loop every time. How is it possible that these can't be disassembled? I mean, you put it together, why can't you take it apart? How can it be cheaper to produce a product like that? Why would Marzocchi do something so dumb? Do they just expect us to buy a whole new fork every time we wear one out??!?! Sheesh. I don't expect a real answer, just venting I guess.

So here's a pretty basic question - how long do forks last before they need new springs or rebuilding?

well, i need to say that you can change the springs, oil, and seals on marzocchi forks, but the cartridge is somehow unalterably fixed in the fork bottom.

if someone were to donate marzocchi forks to people with machine tools like me or Alex, we may be able to simply mill a cross section of the fork bottom to figure out how they're made. then a few more forks bottoms would probably be required to figure out if one can machine them to convert them to being revalvable.

now, springs probably last forever-ish. yeah, they may fatigue a little, but i think they'll stay reasonably close to their rates for a street rider. not sure about a racer.

original oil is pretty scary and after a couple years, you need to change the oil, as the forks have "broken in" and there'll be lots of aluminum in the oil. seems to get better over time.

I've got a '94 M900 with non-adjustabe Showas

Had them rebuilt with the race-tech kits and they're brilliant, a hoooge improvement.So much more feedback, plushness and a lot less jolts.

The shop that did it were insistant that to get the best out of the kits the racetech oil had to be used.They'd tried other oils and found the results not so good.Racetech oils is expensive but seems to get the best out of their kit.

Maybe thats the source of less than complimentary reps.

Its been one of the best mods I've ever done to the bike.

Does what it says on the box.
