I had one and couldn't wait to take it off, ok someone tell me why a gear drive is better for a street engine? IMO they are about as useful as a pair of fuzzy dice, a total waste of money on a street engine. They make a great paper weight but a rock is cheaper. My last word is this, I'm not a NASA scientist or pro engine builder like some of you guys, I'm just a regular guy that believes in practicality, and to me spending hundreds on a gear drive for the street, just for the noise is, well, impractical when they sell quality chains.
