Pistons CB77E

[Kuno]

My CB77E, (305cc) 1964 is prepared for Classic racing with overzised pistons (347 cc). <br /><br />I need piston rings but can't identify the pistons manufacturer. <br /><br />The pistons are marked with a composed AE and AM, and have cylindic lines about 1 mm deep and about 5 mm in between, all the way from top to bottom. Diameter is 64 mm.<br />(It might be Am. Norris pistons.)<br /><br />Where can I buy piston rings.<br /><br />

Sounds like some one off piston to the best of my knowledge.Webco made kits for these bikes but I dont know what the spec is on um. The ring may have to be a custom deal to work on yer pistons.
