hi im asking for any thoughts you may have on the problems my 2015 gas gas ec 300 has picked up its 4 months old and it has only covered 400km it started on saturday while i was on a run out with friends the first thing i noticed before we set off is the electric starter would not work, i carried on using the kicksart after a couple of hours the bike developed an erratic idle follwed by a knocking noise (pinking) then the bike started to overheat . i decided to get it home there was approx 1.5ltr of coolant gone from the cooling system, ive drained and replaced the fuel and checked for air leaks on the inlet rubber etc, has anyone had any similar issues? thanks for any replies regards rob
