I just picked up a Athena 478cc kit still in original package for my yfz for $300. From some rich spoiled kid. Im sure someone has one here. Is it a noticable difference in power? I have exhaust..jet kit...intake..and rev box.


I also bought from the kid, a blown up yfz. Has Elka front shocks....jansen a-arms...rpm dominator axle...billet accesories...after market steering stem with built in dampning system and bar clamp....steering dampner...aftermarket hubs...steel braided brake lines...all for $700

 

Dude you got a killer deal! If you are parting out the yfz and if the head is still good let me know I am looking for one.

 

Wow, that kid needs to be shot.

 

I would like to get that steering stem from you if your looking to parting out some things.

 

no one can tell me about the big bore kit?

 

I rode a YFZ 460 once and it was pretty quick. I have no clue what else was done to it though. So a 478 with the upgrades you have should notice a difference.

 

So what all did you get with the kit?

 

he said "still in original package" so i assume everything. So he paid $1000 for a 478 big-bore kit and a blown yfz with all the upgrades, wow.

 

it is the complete kit...head..piston...gaskets..rings... I guess i'll just have to c for myself. As for the blown up bike, im switching all my stock stuff and putting it on that bike and possibly re-build that motor....i'll let you guys know if i decide to sell anything

 

Please do.
