I just bought an S40(Savage, LS650) and I absolutely love it. This bike keeps up with all bikes except crotch rockets to at least 60 if not higher. My question is on the 600 mile service what exactly should I make sure that they do. My dealership is a little shady and want to make sure it is done right. Also has anybody had a 600 mile service done on their bike and what is the result when you get it back in terms of performance and gas mileage. Does this service even affect any of those things? Also so far my gas mileage with 550 miles on the odometer has averaged 58 mpg. Will that go up after the service or n
