Re: Two items that could save your life
I will never run a spring tensioner on a chinagirl kit. Its not that hard to get the sprocket centered which removes the need for this band-aid fix. Some bikes require a tensioner, but a spring loaded one is asking for trouble somewhere down the road.
All a spring does is make it LOOK tight, everytime you let off the throttle, there's all the slack on the top chain run.
Take the time to center whatever sprocket you use and you don't need a spring.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
