How long can it sit in the garage? I got an injury on my leg and I want it to heal 100% before I can start riding. So far it's been sitting for 6 days. All I did was turn the gas switch to 'OFF' and turn the engine switch to 'off' as well. What should I do in order for it not to get damaged? Should I fire it up every day for about 10 minutes and then turn it off?
