15w oil in front end

[tommyardin]

NEVER heard of forks locking up, EVER?


The adjusters on top of the forks were useless when i had them, i now have earlier model forks that don't have them and they've been fine for me, although admittedly i'm not normally chucking the bike about at high speed but if that's what you're intending to do then you need to do more research.


15w oil most definitely firms up the front end enough to give it a much more controlled feeling, and i would certainly recommend it over 10w. Some people have even gone a bit heavier by mixing oils but i think that would be a game of luck and chance until you got it right.
And obviously your own weight, top box, luggage and the odd passenger can change matters too.
If you're a lightweight carrying none of the above then you may find standard oil works just fine, but i would say take a punt and go for the 15w as i personally don't think you'll be disappointed.

That is probably because you have the correct viscosity oil in them, or do not ride hard.

I agree totally the pre-load adjuster a  next to useless.

Can you not see though if you have a fluid that is to thick to pass through a certain size hole quick enough when being forced it will slow the compression down to the point of locking, especially if more force is added rapidly as in hitting a fast bump on fork compression, it ain't rocket science.

Do a search on the internet about Hydro Lock how and why it happens, it can happen inside an internal combustion engine just the same, where hyrdo lock can occur in high compression engines, it can bend con rods and fuck engines.

It's Ok that some don't know about it, as it usually does not effect people, but that does not mean it does not happen or exist, ask the poor sod with the bent conrods and/or knackered crankshaft, or the poor foccer that came off his motorbike when cornering hard because because something weird happened to his front end when he hit a bump, it's un-explainable I just don't know what happened.
