Worn rear shock, where to repair or replace?

[ac3_snow]

hello,

at a recent track day was informed that my rear shock in cbr250rr is worn. I'm putting my faith in the mechanic there as I know no different.
Anyway my question is does anyone know a good place in auckland to get them checked out and re-newed? there is one on ol trade me at the mo for $45 which is claimed to be in good condition, however as its the same age theres a good chance would be in the same condition as mine.
Yet could be worth a shot as talking to cyclespot honda they claim getting a shock redone can be between 200-500bucks!
Someone mentioned that I can simply get them 're-gassed'
any more knowledgeable opinions would be great, or a link to thread if this has been already discussed (I did look just not at all two thousand threads!)
cheers

That is a sealed for life shock with a welded up end and is intended to be nothing more than throwaway.

Ther are however people that will do them ( not including ourselves ) by machining apart and some clever adaptation etc. Cyclespot are correct, it would be a minimum of $200 or more.

''Regassing'' is a term used by those who really have little idea of whats involved, all you would be doing is ensuring the gas pressure is within spec, that shock doesnt even have a gas nipple and may just be a oil / air emulsion mix. Given that it will have now done several million cycles on its original 150mls or so of oil the oil will be trashed and bushings and seals worn. Shock oil like motor oil does no magically last forever.

Having it rebuilt by the guy that Cyclespot use for such work will give you the very best result, if you buy something second hand you may be lucky, you may not.

Tjebe Bruin on the North Shore, or Norm Cobb at Supercross cycles may be able to do something with it. If it can be rebuilt properly, then it wouold be better than a 2nd hand one.
