Fork Oil Change
 

Is it possible to replace the fork oil without a complete dismantle of the forks?

Can the tops be removed & the oil siphoned out like petrol from a fuel tank?

I have read numerous threads about changing springs etc.etc. but have neither the confidence, funds, ability or knowledge at this stage, think maybe with an old curvy a fork oil change may help if I can make it a relatively easy job.

Thoughts & comments from experienced spanners will be read with interest.

Thanks OG

In my albeit limited experience, I dont see how you'd get all the old oil out without taking the forks off the bike and turning them upside down.

If your going to do that, you might as well change the springs whilst you're at it. Spring change isnt a massive job.

Yes they can, you can remove the top caps and the oil can be poured out AFAIK. Obviously if you take them out of the yokes...

I wait with eagerness for a spanner person to come along and correct me cos I nay be wrong.

Yeah just remove the top caps. Pour old oil out.

You only need strip the whole leg if you are doing seals/bushes/whatever.

Everything from Red Line clear stuff at 5cSt, to spectro golden american 4 20w50 at 155cSt.

Usual viscosity for SV is a 10w at 30-45cSt. (those viscosities are at 40deg C.)



P.s the w rating doesn't tell you how heavy the actual oil is. There are some "5"s that are higher viscosity than other "10"s.

Interesting that.

I was told that my Matris cartridge emulator kit was supplied with 7.5 weight oil. There was no indication on the can and am curious to know if the weight exists.

All make a 7.5, or most makes you can mix 5w and 10w to get same.
