Changed my 800gsa for a 1200 GSA. 2014 blue enduro pack XE. I'm getting used to it. There seems to be a odd vibration on a closed throttle as you come down the revs about 5,000 to 3,000 rpm. I haven't nailed it down yet but it feels just like riding over the roughend markings they pot at the edge of carriage ways to wake dozy drivers. Any one else have this? Or do they all do it? Looking into the fuel filler there is a long tube to stop people over filling and leave room for the fuel to expand. Anybody drilled/shortend tube to increase fuel capacity. It could be done on the older gs and RT. JJH
