I bought an 05 450x used. I was going to make sure the pilot jet was set to 1 3/4 out. The guy i bought the bike from put a crf's only t-handle jet in. The problem is he had it siliconed in, so i took it out and tried adjusting it and it fits loose when adjusted out like it will vibrate out. I dont know if it is missing pieces or what is going on but when i pulled it out there is no spring and only one o-ring on the jet. Is that right? I would like to use this jet but I dont know if all the parts are here and if not can i get them.
You might need to look up into the orifice just to check they aren't stuck up there somehow, the spring pressure is meant to stop the screw from loosening itself
