Preload adjusters for 02/03 forks.

Found these on eBay. Says they are preload adjuster caps for the earlier model forks.
Are these for real? I've got 04+ adjustable forks so I don't want them but I am curious. Would these work on earlier non adjustable forks?

Looks to me that they would place more pressure on the spring seat the more they were tightened down. They would have zero effect on valving though.

Correct.

Further, if one has an 02 or 03, I'd think the bigger pursuit should be adding rebound adjustment capability, especially if the front is resprung to be stiffer.
And that means getting later forks, or swapping in later fork internals, or buying aftermarket cartridge kits, or using F4i forks.
While I'm on it, I'll also repeat that F4i internals can not being fitted into 919 forks.

Is it worth the effort to get the adjustability of the 04+ if you have the 02 bike ?


I have aftermarket cartridges and things that I'll be putting in; wondering if I should bother with getting some 04+ guts into my forks or no...

Do you mean valve kits or cartridges?
My guess is you mean valve kits.
If you are going so far as to put in valve kits, 04+ cartridges have the external rebound adjuster which is a pretty important feature if you are serious about front end settings tuning.

Yeah valve kits, I think we already talked about this in PM :P


I think i'll just stick to getting the kits installed with:
10W oil @ 140 mm height with 15 mm of preload.

Just in case I have inadvertently lead you astray on the point of the respective oil viscosity to use:5 wt for the Racetech valve kits.
10 wt for stock forks, no Racetech valve kits fitted.

Just putting this out there. But if you were to keep 02 forks and not get 04 would these preload adjuster caps be better than nothing? For setting ride height?
Check out wreckers for 04 forks. Probably bent and rusty would be fine for internals?
I see Partzilla still have 919 parts discounted. Maybe buy new 04 fork internals and fit into your 02 forks. There is a good write up on it about here. Some great pics too. If they still load up. Sigh....

For sure.

I've wondered about that too, but a badly pretzled fork tube should also mean bent internals.

It would be interesting to know how many $$$ the necessary parts list would total up to.

I'll keep things simple for now tbh. Don't want to drop any more money than necessary, plus I'd like to do this kind of stuff myself but I don't have my own garage and I don't want to gut my bike in the building garage.


Someday though, I'll turn it into a helimech 2.0 bike :P
