Re: what did you do to your motor bike today?
Its not a china girl, and the chain length and how it is tensioned is not relevant to the wheel or the sprocket adapter. It is a 98cc minibike engine, and I have no choice but to use an idler because of the way my gearbox is designed. Without a tensioner, the chain will rub part of the gearbox. But I use the spring-loaded idler, which absorbs most of the force that might otherwise pull the idler into the spokes.
