Went for a short ride tonight and ended up pulling the dragon back home. Was going wide open when everything shut down and sled coasted to a stop. Pulled plugs and clutch side was dark opposite side was light tan. Motor did fire up but ran noticeably rough. Called my dealer and they speculate I may have one cylinder sticking, they have seen on a 600 a gasket getting sucked in resulting in a blown motor. Anyone have a similar issue happen or have any thoughts. I am dropping off at dealer tomorrow and sure am glad we took the four year warranty when we bought new.
