Description

Round Tip Rocker Arms – 196cc Clone & Predator 212 Non-Hemi (Pair)


Upgrade or replace your factory rocker arms with this pair of Round Tip Rocker Arms, designed for 196cc GX200 Clone engines and Predator 212 Non-Hemi cylinder heads. These rockers are direct OEM-style replacements commonly found on early non-hemi Predator engines, Tillotson 196R/RS, Ducar 196, and other Box Stock 196 racing engines.


There are two main rocker styles used in Clone-class engines: Square Tip and Round Tip. The Round Tip rockers were standard in earlier models. Both rockers may vary slightly in rocker ratio. Although commonly referred to as 1:1 ratio, they may actually measure 1:1.05, 1:1.1, or higher—affecting valve lift and legality in regulated racing classes.


This makes rocker ratio correction critical when checking or optimizing running lift. Most kart racing rulebooks allow minor grinding or reshaping of the rocker to achieve a legal or optimal 1:1 ratio. You can also use this ratio variance to fine-tune lift when trying to match a camshaft to the maximum allowed specs.


Key Features:

  • Includes two (2) round tip rocker arms
  • Compatible with 196cc Clone, Predator 212 Non-Hemi, Tillotson 196R/RS, Ducar 196
  • Common on early model non-Hemi engines
  • May require adjustment to achieve exact 1:1 rocker ratio
  • Ideal for Box Stock, Clone, and other regulated kart racing classes
  • Can be used to fine-tune camshaft performance and valve lift

Note: These rocker arms are not guaranteed to be a true 1:1 ratio. Check with a dial indicator when precision is needed for tech inspection or max lift builds.

  • Predator 212 Non-Hemi Heads
  • Tillotson 196R/196RS/212R/225RS
