Just been out on my 1200 gs, 300 mile round trip today which is first big run after it's service (6000 mile ) & it is very smooth & quiet, but the thing i noticed the most is before the service & since i have had it from new, is it was very lumpy if i let it go below 2500 rpm unlike my 1100gs which was fine down to 2000 rpm , since the service i can run down to 2000 rpm in top & it will pull clean & smooth ,the only down side seems i have lost some mpg
