Description

Primary chain tentioner to suit 9E 10E 11E 31A 32A 33A 34A 35A 36A 37A 31C and 2L Motors. These are fully adjustable, take 5 mins to fit, and no machining at all is needed. They have been comprehensively tested over months including many long distance trials. They are perfect for taking up slack and quieting motors, much easier than taking it apart to add new gaskets between engine and gearbox.

Please let us know in the notes what size primary sprocket you are using. 

Many thanks
