You can upgrade to the later 3mm Tappets/lash adjusters which offer a huge improvement in oil circulation in the heads, thus eliminating the ticking sound that incessantly emanates from the top of your motor. While the opening at the top of the lash adjusters of early models is less than 1mm, the opening in these is 3mm, allowing for much better lubricated rocker arms and a quieter non-ticking "Time Bomb" of a motor. :-) Each and every Tappet is inspected for defects, hole size etc These are a quality manufactured part unlike some of our competitors The reason they are cheap is simple - we buy in the 1000's and pass the benefit of that onto you the customer, if your not happy we will quite happily charge you what our competitors are selling at !
