The Cylinder Works cylinder appears to be and exact replica of the OEM, fit and finish are top notch. All power valve parts need to be transferred from original cylinder and fit as they should. This kit came complete with a matched Vertex piston, wrist pin, clips and upper rod needle bearing as well as all gaskets and seals needed for the rebuild of the entire top end. Installed on a 2021 YZ 250 after a catastrophic piston failure. The bike was raced 4 motos with only a few heat cycles on the cylinders works replacement and performed flawlessly. The new cylinder now has about 15 hours on it with no issues. Would highly recommend as an option to a new OEM or replated cyclinder.

Rebuilding a 2000 yz250 and when taking the power valve apart noticed the OEM valve cracked off. This fit perfect and was a great alternative to OEM

Great upgrade for my 2014 FE350. Noticeable power increase. Great fitment to the stock lower.

Worked Great. Fit great. Came packaged well and has not had any problems since the installation around a year ago.

I blew a head gasket last summer and had to order these. I think it blew because I got too much oil on the stud when I lowered them in and it got on the head gasket and leached under it. The new gaskets worked great since.
