Anyone know how long they were meant to last for in the first place?
Front end is a bit spongy, do I just change the oil or fit new springs while I'm there I'm thinking.
I'm assuming that the current springs are 30+ years old but who knows??

You never know, someone prior to you may have changed them in the recent past.
Measure the length of them (specs are in the Haynes /Yam manual and someone will know here) , thats the way to see if you need to change them or not...

Theyre always shorter than new it seems as just a few miles kills the OEMs.
I agree with Copper, you should always see what youve got first. Ive found progressives in half the ones ive stripped recently.

Thanks chaps, I've never even tried upgraded springs on previous LC's, can you notice much difference for normal road use?
True that I don't know what I currently have,...guess I've got to at least remove/measure them first, refit with new maybe thicker oil and go from there.
Haynes says engine oil 10w/30, any recommendations on using something else??

I have to say that the Goki tops Ive got on my 51LC build have helped the forks a lot compared to not having them. Same progressives in both bikes. I know these air caps are not ideal, but im shocked at how much better it feels.

theyre on my 251LC build, they just add air to the forks is all, like the later ypvs. Easy to make and people will say they are crap on the ypvs, but as I said my initial feeling is that i like them. They only add preload of course.

RZ forks springs were too soft for purpose.. back when the bikes were Brand New
No idea IF they have softened over time.
As first thing one does on an RZ is go for a higher rate spring (either by cutting of 4 coils..or More)
Or fitting a decent grade of higher rate linear spring.
Best Fork Oil I've found is Mobil 1 ATF ..
Yesss autobox fluid. Absolutely reads as an 'odd' choice'
It has a proven centistoke rating performance equalled only by BelRay HVC fork fluid.
Proof is in the use.

hey bare
Reading your thoughts with interest, you say cut off 4 coils, what do you do to add in that extra space?
I've never had much success with the addition of air to forks of any bikes I owned in the past, it was ok for a day or so then all the air leaked out PITA to get the correct pressure in let alone equal on both sides, so just gave up
I'm about to rebuild my forks when I get the lowers back from the coaters
Cheers

Haynes says engine oil 10w/30, any recommendations on using something else?? I rebuilt my forks last year, the springs had already been uprated and I put it back together with 10w fork oil(cant remember which brand but I/you are not going to notice the difference). Oil weight depends mainly on our weight/riding style . For me, the biggest difference came from the fork oil, there wasnt enough in it in the first place, which was why the fork was pattering... |
