New! USA Made Triumph CEI Twins Tappet Adjuster Set. You will get the four tappet adjusters as pictured. Want to extend your valve train life considerably? Well, these new tappet adjusters will do exactly that! Machined and hardened to Rockwell 58-60 right here in the USA! Whats the difference from the "Mushroom" and the stock type tappet adjusters? The "Mushroom" head design limits valve tip wear due to its spherical shape and pushes on the valve tip much smoothly. The original type uses a flat surface which will cause premature valve tip damage! Tappet adjusters measure 5/16" with a thread pitch of 26 (CEI) which mean you can use your original tappet nuts! Fits Triumph 650 & 750 Unit models (T120, TR6, TR6C, T120TT, T140, TR7 & T140V) from 1963-1977. May fit late Pre-Unit Triumph models. Please refer to your parts catalog for proper fitment.
*****Please note that this set is not compatible with Triumph 1978-1988 models as they use a different adjuster.*****
