    works fine

    Went in okay. One of the top o-rings was a pain in the ass, but it seemed to work out in the end. It recomended drilling a hole, but my old piston didn't have one, so I didn't feel like drilling my brand new piston.

    its f****d

    Had my brand new Wiseco top and bottom end put in about a month ago in my 2002 Honda CR250r. Less than 10 hours and changing my fluids twice bottom end seized yet again. Biggest piece of crap I've spent my money on, wouldn't recommend AT ALL.

    Top end bearing

    Good OEM substitute. Used one on my last top end without issue.

    Gasket kit

    Good quality gasket set. Had everything I needed including multiple thickness base gaskets to properly set head space. Would buy again.

    Shim Kit

    Glad I bought the kit, better than buying individual shims at the Honda shop. Fair price, quick delivery.
