Wisconsin top end kits kx65 kx 85

New Wisco top end kits for KX65 and KX85. The fit was great and had no problems at all- the bikes have been running good. My only recommendation is that you have to let the bikes warm up before you wind them out. You might get a little piston slap or nock.

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
