Just getting done putting a new piston and gaskets in my 2002 yz426. I found a great deal on a hotcams auto decompression cam so I'm in the process of getting that all wrapped up. Here's my problem. I install the tensioner (that checks out by factory manual specs) and it doesn't seem to automatically get the cam chain tight enough. I can roll the tension on manually but I'm not sure I'm confortable doing it like that (i figure it's automatic for a reason). So a few questions.... Does a cam chain tensioner automatically adjust tighter, and looser. Or does it just tighten up as needed. And do the symptoms that I'm talking about indicate that the cam chain tensioner is bad. And yes, I know the best way to go about it is to replace the cam chain and tensioner. Thing is it's raining here in the desert, riding is prime, and I don't have the cash to buy the tensioner and chain for about a month. I'm bummed that It's not ready to ride this afternoon!!! At the same time I don't want to wait a month, buy the new tensioner, and have that not be the problem.
