    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.

    Was good...

    Fit great and was an easy installation but blew it first time I took it to the track.
