Rear shock rebuild
 

We are in Jakarta and looking for somewhere who can provide the high pressure nitrogen. Any Suggestions?

I assume you've tried local MC shops? Or suspension specialists?

You may find help over on ADV Rider, thumper forum, DR650 thread.
This thread is huge ... so just post your request for help. That thread is pretty international, has guys from all over the world riding DR650's.

Or try local HUBB community for Malayasia.

It's likely your shock needs a complete rebuild .. which CAN be done, even though some say that KYB shock cannot be rebuilt. IT CAN. There is even a tutorial on that same thread I posted the link to above. Ask for help. With the right tools and few basic parts your shock can be BETTER than new.
Re-Gassing it is only a "half-assed" fix. It probably needs a bit more.
Good luck! Have Fun!! bier

As an emergency thing .. just use air.
Some tyre places provide nitrogen for use in tyres .. you might get lucky there.

If the pressure has leaked out then you need new seals, other wise it will continue to leak so you may as well use air.

Pure nitrogen is better but air will do (fades with heat etc) until you find someone with nitrogen.
