I'll tell you what I did today, then you give me your thoughts-
It's a gusty, cloudy 72 degrees outside...
Not totally out of the ordinary for November here, but these days come few and far between.
I pushed all three bikes out of the garage onto the drive and started them all. Once they were all warmed sufficiently to run without the application of choke I left the two 'Wings idling and rode Pizza bike eight miles, including a blast down the highway to click my way through all five gears up to (ahem...), highway speed.
I brought the Guzzi back home, left it idling, mounted the '89 'Wing, and did the same thing on it.
Then while the Guzzi and newer 'Wing idled I did the same thing with the '87 Interstate. All three bikes ran/idled for 30 minutes before I shut them down and put them back under roof.
I know it is important to allow an engine to warm enough to boil moisture out of the oil, and running them for 30 minutes should also be enough to recharge drained batteries.
But is there a better way to accomplish my mission than doing it this way?
