| I don't know these regs - useful aren't I?
I am guessing that the first stages will be the same as forever - which ones are (or were) they 'cos I think that the flow through piston type is the preferred DIR version. (these piston types are DIR however there is an old failure story about them that it just horrifying beyond belief so it also has to be your decision as well as DIR)
With respect to the second stages it should be no big deal to check. Can you remove the "hubcap" cover without a million bits running all over the place and hence clean out any muck? They will probably have a little pin to stop the cover from unscrewing inadvertently - some say that that pin should be discarded to make them DIR.
It should be all OK but why rush? Wait until someone who knows and has one in their hand can give you a definitive answer.
