Interesting fact about Athena 480 kit

7 posts in this topic

I think Athena uses the same kit for the YZ's as they do the YFZ's. this is pretty interesting, i fount it on a ATV fourm and anyone that has/wants a Athena 480 kit should read this. It dosn't mean the kits are bad or anything its just something that needs to be considered. Seriouse damage could result if not considered:

I think CP makes a different piston for the YZF than they do for the YFZ. I have almost 10hrs of hard riding on mine and I am running the Cometic gaskets too. Bike starts easy and runs strong with no problems. The piston is the 13.5-1 but is not the Venom model.

I'm not sure about the thickness of the two different gaskets.

I did some checking on the CP pistons website. The 98mm piston for the YZF is a 13.5:1 and is part # M1051.

The 98mm piston for the YFZ is a 12.5:1 and 468cc for the 03-05 and is 12.75:1....478cc for the 06-08. The part# is M1009 on the quad. Also they both have different part #'s for the pins.

Also it says to bore and replate on the YFZ but on the YZF it says sleeve or cylinder.
