I recently bought this bike used with 1800 mi on it. Other than the idle setting being wrong and a vacuum hose needing to be replaced, it seems to run well. It starts easily and is quiet and quick enough. MPG has been 93 mpg on the first tank of gas. Gas must be pumped a bit at a time or it splashes back. Premium is specified. The ride is fun though a bit bouncy. Overall, I like the bike and hope it will give good service.
