Found these but seems damned expensive to me, no idea how much Cruzin charge for the same amount. https://www.ebay.co.uk/itm/Honda-CB400-Four-Piston-Rings-Bolts-Kit-Original-0-25/254706583305?hash=item3b4db20709:g:MC8AAOSwV6VfTgYW
Cruzinimage are in Japan. Extremely easy to deal with and buy from. If you can't find someone more local to do a rebore, we (That's Graham, Trigger) do rebores etc and 90% of the engines are sent to us and returned via courier, so it's all very easy really.
Just as a point of reference Julie, I've a spare set of barrels that are passed their best and going on a separate build that need some attention, where its been sitting for years the rings have marked the barrels and could do with a rebore and new pots. What would the ball park cost be for that with you and Trigger?I've done my first Cb 4 mill now so keen to do this one now its all fresh in my head.........like yer do cheers in advance
