I have a 98 wr 400 and it won't start its been at the dealership all year and they can't seem to get it to start either. I have replaced the exhaust , new timing chain, new stator, new flywheel, new seals in the carb, new valves. I have had the tps set to spec and she has lots of spark. the only way to get here to go is to jump start it. Anyone else have issues like this with a wr 400???
