How do you remove that plastic wedge from the inner reeds?
If you have the V Force 3 reed valve the replacement petals are the same as a CR250. The product code is 3P682M. I just installed a set.

You could run a line of masking tape across the top of the reed block under the petals where the petals clip on to the block to tighten the petals towards the block closing the gap but if there chipped change them..So I took a peek at my V Force 3 reeds and I could see slivers of light thru the upper and lower reeds in the upper right lobe. I took both out and flipped them over thinking they would seal, but no. Time for replacement?
That code (3P682M ) fit on my 2007 ec250. I don't think there were any changes from 2007-2009 models.
