I have an '05 888 with a rebound issue. It compresses fine, and rebounds fine, but on the rebound, there is this annoying "suction" sound coming from the fork. It started after a weekend at Windrock. I've tried burping the fork, but that did not help. Could it be low oil? Has anyone else ever had this problem? I tried searching this thread, but couldn't find anything with that issue. Any help would be appreciated.
