rad valve spacer

[gassergrant]

Just rebuilding my ec 300 2003 after my reed valve gave up, i'm putting some pro series in. I've been told that the spacer in betweed the rad valve and engine. if left out, gives better results.
has any one anything on this.

more preference I think. You should try it with and without and see if you notice the change and share the results.

Taking the spacer out makes it more aggressive or hit harder i believe. I would reinstall it, unless your a motocrosser.
