umm , thats not good . the oil or black crud all over the valve is normal , its due to running cheap oil , run a high grade oil and it will drasticly reduce this problem . your rave valve should look like this -----}}} if it looks like
------ and the }}}} is broke off in the engine then you need to check for piston damage by looking thru the rave port and turn the motor over any gouges or deep scratches will need to be fixed , you also need to check your compression , if all looks good then you lucked out big time and i would replace both rave valves and rebuild the diaphrams with them . here is a pic of a broken one http://i25.tinypic.com/20hq15z.jpg and here is a good onehttp://www.powersportspartsplus.com/catalog/ccc1_1_59_1_thumb.JPG

Usually you see that problem with the early 787 rave valves like the one's that came in the 95 xp limited. I would go with the newer slotted rave valves when you do replace the top end.

I'm sure that the rave valves that sbt sent you will be ok. There is a updated version that have slots in them but both will work ok.
