Air/Fuel Ratios
Is your engine running properly? Got a flat spot in power? Is it lean or rich?
If so, it can mean really costly consequences.
Whether your bike runs carburettors or fuel injection, you need to know that they're doing their job properly.
Not only can it save you money on fuel, it extends the life of your engine, and gives you more power. It's all win-win.
This guide tells you how carbs and efi work, how to diagnose what's wrong or how to improve it, and tells you how much you can expect to pay for it.
