You really don't do it any favours by leaving it idling for prolonged periods from a cold start, it's contaminating the oil film on the cylinder bores with fuel and condensation, which reduces the service life of the oil and increases wear rates on the rings and bores. Also idle is about the worst condition for valve train wear.

Start it, let it settle for a short time for the afterstart enrichment to ramp down or just long enough to get the choke off, typically no more than 30sec is needed, then ride off gently.

As said, gradually ease the revs and load up while it warms up fully before using high power/revs.
