Jeremy_bell_banshee99 Posted March 28, 2012 Report Share Posted March 28, 2012 I got some Athena 392cc cylinders for the price of some spare yz490 parts. I read all around here, people say that they are no good... but why? I don't need directed to a different set-up. This will be my spare motor set-up. What's the deal with these cylinders? They look real good and clean, have never been ran at all, I just wonder why they are "junk" when Athena is a big name in big bore kits. Thanks.

Jeremy_bell_banshee99 Posted March 28, 2012 Author Report Share Posted March 28, 2012 Have u ever compared them to ported stock cylinders Quote Link to comment Share on other sites More sharing options...
GORT Posted March 29, 2012 Report Share Posted March 29, 2012 I was thinking about buying this kit too. From what I have seen there right around 700.00 on eBay. A lot cheaper than most other kits I've looked at. Input from people who have run these kits would be nice. We're they everything you expected? Would u recomend them to others? Do they really give u 10+ hp by bolting them on? Thanks Quote Link to comment Share on other sites More sharing options...

Remus Posted March 31, 2012 Report Share Posted March 31, 2012 The athena cylinders tend to have shite plating, some hold up, and others just come off like icing sugar. Quote Link to comment Share on other sites More sharing options...
