I showed the Kip Springer tensioner to my neighbor who by the way is a mechanical engineer for NASA. His statement exactly, its looks nicely done with the solid mounting to the case and 100% better than the "suicide tensioner" that came with your kit.

Just because you're a tool and can perform miracles on the cheap does not mean everyone else can do the same with good results.

There's not a doubt in my mind that if you took a poll on what causes the most problems in setting up a motorbike, the rag joint and "suicide tensioner" would be pretty close to the top of the list.

Whatever. I disagree with your tone acting like you NEED these parts or you will die.
No matter what you tell me, I know spring tensioners are a poor solution in any setup that has variable speeds and loads. Over 30 years in all types of industrial power transmission repairs tell me you are misguided. If your sprocket is so well centered, why does it need a spring anyway?
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
