Rear shock preload
« on: December 16, 2012, 07:49:27 PM »
Hi Guys I must be going loopy, I'm sure that I remember reading on this wonderful and extremely helpful site an article on topping up or refilling the oil in the rear shock preload adjuster. I've looked everywhere and can't seem to be able to find it, can some one please point me in the right direction.

Just done this job. Took less than twenty minutes. I cracked the banjo before undoing the two M6 bolts.

Unclip the hose from its retaining clips and worked from the left side of the bike only. Once the hose is loose you can raise it high enough to prevent air from getting in and just hook it up with a short wire.

Used 5Wt fork oil. The difference is noticeable the moment you drop it off the stand.

Set the STD. Now to set the rest up properly.

I wonder if this is why my bike feels so close to the ground.

I have to have 100% level ground for my side stand to work with out tipping over ..... or a slope to the side the side stand is on.

This might also help with steering as well??

Post a pic Spanner.

Goes without saying if your rear end is sitting much too low then your rake angle has been altered as a result. If the rake angle is being compromised then everything about the bikes handling will be different and not always apparent.

For the rear end to be so low as to affect the side stand more needs to be investigated. Starting with the side stand itself.


The most obvious thing with the pre load recharge was stance and no slumping once I got on.
I've just finished putting all the other shock adjustments back to STD. Over the weekend If Im feeling well enough I'll ride it and set the show up for me.
Seems the last owner tried to amend the preload issue by cranking it on as far as it felt ok then hardened up the damping.

Its entirely possible that teh previous owner may have replaced the shock with a slightly shorter version, maybe even to lower the seat height. Or the shock has collapsed. even.

Hey Spanner - a lower profile rear tyre will give the same problem too.
