Try the technique that I use. When I park up, even for a short while, I rev the engine, close the air lever/choke and hit the kill button. This leaves a nice rich charge in the crankcase for restarting. Leave the air lever closed and kick the engine over. It will usually start first kick. Open the air lever as soon as it fires up.
For my bikes this works most of the time (you can never say all the time with Scotts!), it usually starts first time whether it’s a 5 minute stop or 5 days.
