Ive got a 2004 based yfz450 engine for sale.

It has a WR crank, and a WR high compression 13.75:1 piston. The piston and crank are in great shape. I was building this as a spare motor for this year and never used it.

It has a new clutch
New gaskets, exhaust gasket, main bearings, seals, anything that you use new when you take apart. I took it apart to put new main bearings for a fresh bottom end.

Everything is stock, it will make for a good powered engine.
Contains kickstart as well as electric start. The motor is ready to be dropped in and go. Freshly pc'd case covers and valve cover.

$1400 includes the installed hotcam intake.

I rebuilt this motor from the ground up replacing anything it needed, as stated, new gaskets, new perishables, and everything

Stock head yes sir, stock valvetrain

The crank is an OEM crank and the piston is a CP piston, I wouldnt run/trust anything else. My race motor had the same piston as well.

If you want it, ill install a hotcams intake for you as well as the cam mod.

Here are pics to prove all the new stuff, i tried getting pics of the stuff beforehand
