Cx and gl forum is a great community like here, yes, well worth the risk of anything. Inspect with a mirror and light to ensure your timing chain tensioner is working and there is good life on the blades. David Silver Spares carries a good selection of aftermarket parts of good quality, but you can get good discounts on parts at South Sound Honda in Olympia, Washington when going original Honda parts.
I believe Parts N More give CX members an extra 5 % off for some services of the CX forum did for them. Details on that forum.
