Always a quality product
Athena always provides a quality product. I never have concerns that a repair will have to be redone due to poor sealing.

ATHENA BIG BORE GASKETS - 144CC
Only reason I would recommend this gasket kit is because you have to use it when using an ATHENA kit with their head design. *I have used a complete ATHENA kit twice (piston, cyclinder, etc) on our personal race bikes (2008 & 2010 YZ125) -and also installed them for other riders with varying degrees of sucess but nothing better than OEM. I would not recommend this application for a MX racer and have seen limited sucess with GNCC type racing. Talking with other mechanics they have experienced the same things. Love it or hate it, no inbetween. The trend I have seen is lower rod bearings or thrust washers burn up which also leads to the crank stuffers melting. Yamaha does not sell the nylon OEM crank stuffers seprate which leaves you looking for a new or used crank with good stuffers= $$. Dont get me wrong, the gaskets are fine - it's all of it together that we have had preformance issues with.

Is the cam chain tensioner the same gasket as oem?
I have an 05 CRF250R with the 280 big bore kit. my cam tensioner is leaking engien oil because the gasket went bad. I was wondering if i could just buy the OEM honda one and put that on. will the OEM fit on the big bore one?
I have a 280 Athena kit on my 04 CRF250R. I am having some work done to it and they told me I needed to replace the rings. It's at a Honda shop and this isnt a Honda part. Would these gasket kit be what I need if I need to replace the rings??

This actually the gaskets for the 280cc kit, if you need the rings unfortunately you will have to purchase the piston, which will include the rings: http://www.motosport.com/dirtbike/product/ATHENA-280CC-BIG-BORE-PISTON/?catalogId=100477
