Last week I put a new clutch in my DRZ400. I had read that a KX500 clutch works as that was what the GNCC and WORCS guys were using back in the day in their DRZs. I put a complete KX500 clutch in my DRZ and also found that the pressure plate is exactly the same between the DRZ and the KX500. What Im getting at is it may be possible to use a auto clutch from a DRZ in a KX500.

The big question for me is can the Rekluse hold up to 70hp at the rear wheel and remain reliable...
Any thoughts?
They make them for Harley's and all the big adventure bikes so I would be inclined to say yes.  Is Revloc in Australia only now?  They closed up shop in the US.

I spoke to EFM and they will make you one e for $650.  Just gotta send a basket to them and then you need the Billet clutch cover spacer I've seen floating around the forums or on the Facebook KX Guru page. Don't remember how much they were asking...?
My KDX EFM clutch has an aluminum spacer in it.  The one from KXGuru is to convert your cover to a two piece unit.  I don't think it would be thick enough.

All I could find for Revloc was the Australian website and a few places in the US that stock them.  Do you know how far out the Rekluse guys are from releasing their clutch?

To mod for the AFM you could still use the KX Guru adaptor ring,  just don't machine as much off the cover when you install the ring.

Or, if you already have a two piece cover, buy another adapter ring, drill through holes instead of tapping and you have a perfect spacer smiley

The spacer on my EFM is about 1/2" thick, while my KXGuru adapter is closer to 1/4". I guess I wasn't thinking about cutting it off a little higher so the two piece cover would clear the auto clutch. That's a good idea. I would think EFM would also have some sort of solution for people that buy their clutches for the KX 500.

Yeah, the adapters start at about 1/4" thick but do end finishing a few thousands under..

Umberto, can you give us a review on your EFM?

The clutch itself works really well. I think it hooks up even a little better than the Rekluse in my 250 that has the medium springs in it. There are two things I don't like about it: you have to push the bike and then put it in gear while rolling the first time you start it for the day, and there is no clutch lever to fan if you get in a jam. It makes you really use your transmission. I think on a 500 it would be great in the woods, but maybe not as fun in more open spaces. It does seem to be durable, as everything else on the bike was clapped out, but the clutch still hooked up like a champ.

I spoke with the guys at EFM today, just to follow up on what 198mcneil found out.  They said you would need to send them your full clutch, and it would take 3-5 days to get it completed.  I guess their newer models are a little different from the one in my KDX, because you can still use your clutch lever with this model.

Okay. So the whole thing needs to go. Sorry about the bad information on the basket only claim.
That's great that the clutch is fully usable now.
Did you get any further clarification on what kind of cover or adapter is needed?

He said that all you need is an extra 1/2" spacer, and that the two piece cover makes it a lot easier to install.

So I ended up purchasing a 51 tooth rear sprocket.  Seen quite a few people online have used them.  Went to put it on and it was to big.  Meaning it hit the black lower chain gauerd.  I didn't want to mod anything but I'm interested in trying this gearing. 
Is it safe to run the bike without the lower chain holder and just use the teflon guides?
What is an easy mod to lower the guide and holders?  Maybe just a plate with some holes drilled in it that drops it an inch?

Thank you
