Selected User Reviews For sthus 80cc Motor bike GAS ENGINE parts - SPRING bearing chain idler tensioner & PULLEY
I got two of these for two bikes and one worked barely, and once put together, there was no tension applied, and they didn't even move once bolted in. They are a good concept that needs improvement.
You only need to replace the spring with a heavier duty spring for this tensioner to work!.
The bearing for the tensioner arm is welded in at the factory (and seized). There is a problem with the clamp bolts being soft and a little too short. If you fix that issue and put in longer, harder bolts, everything will be fine.
Nothing but a waste of time. I want to address the people who claim that if you change the spring, it works perfectly fine. Can you tell me why the spring needs to be replaced? A stronger spring should have been included with it. There is no picture of it because I was removing it off the bike before its bolts could be torqued.
I've never had a chain hop since using it!.
