The Tillotson 196R for the Box Stock 196cc Class has been discontinued

The Tillotson 196R Box Stock racing engine was developed to meet the technical specifications of the AKRA, NKA, and WKA rulebooks. 

Tillotson’s goal is to have the first ‘spec’ 196cc box stock engine that never changes from batch to batch. Tillotson has accomplished this by building their own factory and assembly line in china. This eliminates the struggle importers and dealers have with consistency by Tillotson having engines purposely assembled to tighter specs for the box stock class, not a generator engine with a good flowing head. Tillotson sought the best quality manufacturers and have cherry-picked parts for their engines.
