    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.

    Great Part

    This chain was replaced to mesh with a new front and rear sprocket. It has a nice appearance and is durable. I put my KX450F through a brutal course and when clean up maintenance was done, there was no measurable chain stretch. I think this is a high quality part.

    Perfect as expected

    This part was replaced to match the J.T. rear sprocket. It is of high quality and is machined for a perfect fit. I am very pleased with my new rear ratio.

    Great Part

    This sprocket was a perfect fit, and has a good appearance. It gave me more bottom end which I was looking for. This already renowned part is everything it is advertised to be.
