September 10, 20178 yr I have a 2017 4Rt with about 60 hour on it. At the end of a ride after making a two wheel landing (solid landing but no major crash or anything), the engine started making an odd ticking noise - sounded a bit like the kickstart was engaging. After it cooled (next session), the sound had gone, so I rode an hour session with no noise. Then after another 2 wheel landing (hop from a 1 foot ledge), it started up again. Loud at first then dies off. After it cooled, sound gone. Recently changed oil filter - maybe 2 hours ago. Otherwise no works to speak of... Anyone has any thoughts?
