I have the top end on my 09 Road King disassembled because of a chirping noise that couldn't be easily identified. This is covered in a recent post and you guys were super helpful. The working diagnosis is piston slap (for whatever reason) and my new pistons are on the way and I have a machinist lined up to take the cylinders 10K over. I'm trying to decide if I should go ahead and change the tappets, push rods and rockers. It's a big bore 103 kit. The HD mechanic said no need to fool with any of that stuff because it's in good shape per his inspection. About 30K on the kit. Any feedback on that would be great but here's my main question. Should there be side to side movement in the connecting arms? There is no up and down play, which I was told to check for but the rod does move from side to side, the front more than the rear. Is this OK? Thanks in advance!
