My suggestion; use the "CHOKE," JJNyborg!
First, it ain't REALLY a "choke," it's a STARTING ENRICHER.
When the engine is "cold," regardless of the ambient temperature, the starting enricher, when applied, provides a fuel-rich mixture to the engine for the purpose of . . . well, STARTING!
When you engage the choke lever, you withdraw a plunger from a hole in the carburetor and also open an air passage; fuel flows from the hole and mixes with the incoming air, not unlike the starting arrangement is a "mini-carburetor," only the misture is especially fuel-rich, for the purpose of starting the engine.
Try this, next time you start your bike: Ignition switch on, kill switch in RUN position; petcock ON; transmission in neutral or clutch lever pulled; activate choke lever (choke ON). Hit starter button, 'til engine starts. Gradually move choke lever to OFF position, as engine is able to sustain operation without enrichment.
Your automobile likely has a mechanism richening your starting mixture also, but transparent to you as driver. The KLR650 requires human intervention (activating choke lever) to start easily, most usually.
