Graves Motorsports High Precision Cam Chain Tensioner Yamaha R6

Graves Cam Chain Tensioners were professionally developed under strict guidelines for use in the Graves Yamaha factory race bikes. It is machined from aerospace materials and features a fine thread that allows for micro-adjustability. 

The Yamaha OEM cam chain tensioner is automatic and hydraulic, though great for everyday riding it is not the best for racing applications. The stock automatic tensioners can fail and hydraulic pressure can be inconsistent under race conditions. The Graves Cam Chain Tensioner eliminates these possible failures and allows you to fine-tune the tension and keep in within the set parameters.


Fitment Notes & Exceptions

  • May require a new Yamaha cam chain tensioner gasket and timing cover gasket for installation

So when installing APE manual CCT, I'm told you need to seal off a small oil port/hole just inside where you put the CCT. I don't see that requirement for the Graves, is it required to block it off?
A shopper on Jan 14, 2015
BEST ANSWER: Well, to answer my own question, it does not appear to be necessary. I installed the CCT, and the instructions do not mention anything about blocking off the oil port. I have been riding for a month / 1k miles with no problems or leaks, so I'm gonna go ahead and say you don't need to block off that little oil hole.
