CB500K0 piston rings
« on: June 18, 2019, 04:40:30 PM »
Has anyone used Cruzinimage_uk piston rings?  When I came to refit my pistons yesterday, I found one ring broken.  Many expletives were voiced as the were all fine and within spec when I had removed and refitted them to clean the pistons.

Should also have mentioned if you are unaware, Cruzinimage UK are in Japan. So you need to add about 34% on top of the price of the rings to take into account post, duties and Parcelforce kidnap fees.

Bryan, it is a bottom compression ring (i.e. the middle ring) that is broken.  The rings are standard.

Thanks Bryan

Julie, will duties and kidnap fees apply if the cost is only £36 + £9 p&p.
