This is the buddy from Mino-Racing which I mounted in my KTM four stroke. KTM uses from 2006 onwards a hydraulic Cam Chain Tensioner which gets faulty after only a few hours. I guess it is mandatory to change the original hydraulic timing chain tensioner with a mechanical one to avoid break downs in the middle of nowhere!
In this short Video you can see all action it takes to tension your Cam Chain.
You have to pre-tension it by hand first until the Cam Chain is firm and afterward give it another half to three quaters of a turn with the hex. After that you can fix the counter hex and be shure no problems will occur. Check your timing chain tension every 20 hours or with any valve clearance check!
