I have a 2010 yz450f I've got a 3.0 exp in it has anyone had any problems with theirs. The fibers on the the 3.0 are worn down flat and the Teflon is coming off the wedges. I have a couple friends that have 2010 and 2013 they both have burned up clutches has anyone else burned up the clutch in their bike

You have to keep track of the free travel on the clutch.  If you allow the play to slip below limits, it's just like running around with the lever pulled part way in all the time.  Read the Rekluse manual for setting up the "gain" again.  Of primary importance is the fact that when the revs are up and the clutch is completely engaged, there must be at least the minimum specified free travel at the lever.

 

Another thing that can lead to this problem is setting up the clutch with either or both of an engagement RPM that is too high, or and engagement rate that is too slow, and then spending a lot of time at lower speeds where the clutch is being modulated (slipped, feathered, etc.).  Riders who run a gear too high a lot can fall into this category, too.

 

The one last issue is that the EXP 2.0 and 3.0 (as different from the Core EXP) remove at least two plates from the clutch.  The clutch was already down a pair of plates compared to the '06 and earlier, so things have to be watched a little more closely as to maintenance and such.

I have one in my 13 rmz450f it's flawless. I had to adjust the free
play once after about a tough three hours. after the quakey break in.

On a powerful bike like the YZ 450 there is no doubt that you really need the Core EXP with its extra clutch plates.

My experince with the 2012 Yz450F is that the EXP is only unit that does not wear out quickly. Have had the Core unit on a 2012 for two season of MX and Cross country with my son a line behind the pros no issues The EXP unit would not even hold up on a 250 we tried it on for two races before it slipped under high rpm
