Hi! In 1986, I bought this trx350 Fourtrax that still has the same tires and brakes, didn't use it too much but I have excessive noisy valves. I replaced a worn rocker arm as well as the camshaft that had a worn lobe. No luck, I still have the same noise which I hear well with a stetoscope near the head valve cover.
Any suggestions?
Thank you
