Good OEM substitute. Used one on my last top end without issue.
Good quality gasket set. Had everything I needed including multiple thickness base gaskets to properly set head space. Would buy again.
Glad I bought the kit, better than buying individual shims at the Honda shop. Fair price, quick delivery.
Fit great and was an easy installation but blew it first time I took it to the track.

It was everything my mechanic needed to put my son's YZ80 back together.
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!
