JD jetting has a improved gasket . I bought a used carb on the ftr forum to bore out The guy gave me box full of jets he had tried . I was not aware there was a jet block gasket found out on thumper talk . This carb had oring leakage and a failed jet block gasket no wonder the guy had a box full jets, needles, nozzels ktm should have a carb recall and mikuni fix the gas leaks it is a fire hazard these are small cheap parts . My 250xc has picked up a after bang in the exhaust it still runs just not as good as it did. I bet it has a gasket broken in the jet block. I will order new gaskets and orings tomorrow .Please make sure you cut the petcock off hate to burn your house or camper or you
