So my 06 kx250f was starts making a rubbing noise an it kept getting louder, so i tore it and the piston was perfect, the I put the cams back on to check the clearance again and on one intake I could even fit my smallest feeler gauge in and the bucket is touching the camshaft, I order a shim kit but I'm wondering if the camshaft and buck always touching could make the noise...also before I tore it apart it ran just fine and had the power it always had
