Thanks johncy7....... I'm not meaning to "brag" or ramble on about this thing like it's the greatest in the world because it's not...it has bugs. Nothing is perfect. I haven't had any issues with tensioners in the past. I just like to "change" from time to time. I've never liked the idea of not using a tensioner at all...then again I haven't personally tried it so there isn't much standing ground there. I like the idea of having a little bit of play...but not too much play. AND actually...this isn't the chinese chain that came with the kit..I bought 10 feet of roller chain from my local fleet farm and it's MUCH higher quality..not to say that it wont stretch....but it's not a chinese rubber band...
