  If your Suzuki Motorcycle is difficult to start, begin by performing a visual inspection. Specifically, check the engine oil level and look for any signs of leakage. Next, inspect the engine coolant level and check for coolant leakage. After that, check the fuel level and look for any fuel leakage. Also, make sure to check the air cleaner element for clogging. You should also check the battery condition, throttle cable play, vacuum hoses for looseness, bends, or disconnections, and look for any broken fuses. Furthermore, check the FI light and other warning lights, speedometer operation, exhaust gas leakage and noise, each coupler disconnection, and clogged radiator fins.
