Eric,
I just visited your website and was directed to this forum, I'm hoping you can answer some mod. questions.

Will the Athena Race Cylinder kit fit on an 05 YZ 125? I've been looking so far and the ads only say up to 04 models.

I would like to have this kit and bore it to atleast a 144; but not change the stroke and use the high compression cyl. head.

If this kit will not work on the 05, can I get similar performance by modifying the stock 05 cyl. and head? Would buying an 04 be a better option and using the Athena kit?
Thanks,
Yamahuh

The 2005 YZ is a new design change and doesn't interchange with the 2004 model. Athena doesn't make a 2005 model as of yet.
