Even if your CB350F seems to be running well and is not smoking, you undoubtedly are at least mildly disappointed with your bike's power. Guess what? You don't have to resign yourself to that state of affairs. A pokey bike is not the price of admission to the CB350F. Some very small, simple, routine engine rebuilding techniques expertly applied to this engine yield surprisingly satisfying results. And this without any of the proverbially scary, invasive, fast-wearing and questionable-quality high performance suspects such as big cams, high compression or big-bore piston kits. In fact, it's done with all factory Honda parts.
