Well here is another opinion. Milidon also makes a gear drive. You can buy these in quiet, normal or extra noisey. Yes you can get some loud ones. I love the one's that I have used and will be replacing a brand new timing chain set on this new cobra with an extra noisey one. Nothing like rolling down the road with the sound of a blower......

Ebay has some cheapo stuff on there, I have never used any of it but who I am to say it is not any good. I will say I know what I am getting with a name brand. I believe about everyone makes a quiet one now if that is what you are looking for.
