I have the athena kit on mine for about a year and a half with no issues.

Its well worth it. I use the cylinder works kit, but DO NOT use the Vertex piston that they try and match with the cylinder. Pay the extra $50 and get a JE or CP piston.
The Vertex are crap, and you will get about 3 hours of hard riding before they crack like an egg right along the top of the piston pin, they are worthless. My LTR and a friends identical bike had the same issue within 2 weeks, cost me a DNF at my last race.

How are the wiesco kits. I had the guy who's doing it order me the 474 kit with wiesco piston.
