Was good...

Fit great and was an easy installation but blew it first time I took it to the track.

Great Deal

2008 FZ1- Fit perfectly, no 'big glob of glue' on the end holding the magnet in. Nice black finish, we'll see if it holds up. Same exact length as stock. I'm actually kind of excited to see what it pulls out of the oil at the next interval. Cheap insurance, money well spent!

Replaced the top end on my 96 cr125r! Fit great perform well but the price is the problem. For 70-80 bucks they'd be perfect!

Hammerhead Engine Plugs

These fit perfect, and look great on the bike!! They do not come with O rings so you will have to use your oem ones or buy new ones but they are only a couple bucks- definitely worth the money.

125cc kit

I had this athena kit on my 2003 yz125 and the bike ripped. Probably was the fastest 125 Ive owned and it ran stock exhaust only other engine mod was vforce reed. I called it the blue demon :p
