How long do I let my bike idle after riding (650turbo)

How long should I be letting my bike idle after riding it, The guy I bought it from just said let it idle for a while after riding to get everything out so you don't break the turbo

 

The whole idea behind that, is to let the turbo cool down a bit before shutting down. If the turbo is glowing red, you definetaly want to let it cool before letting it bake in it's own bath of hot oil. If you haven't been riding the bike hard, you don't need to worry about it much.

For instance, if you were out at highway speeds, but on your way home, you have to ride down a 25mph street for 5 minutes, you don't have anything to worry about when you get home. You should be able to shut the bike off right away and not worry.

 

Turbos without watercooling do have a tendency to coke the oil {turn it into cinders} if you shut down the oil pump before it has a chance to cool down the Turbo and its bearing surfaces. This cked oil is like cinders and will do great damadge to the turbo. The old Automobile turbos had just this same problem in there infancy {the early 80s}. I wood have to say you can,t let them cool down too long but you can to little. My sugjestion is to err on the side of caution.
