My Foreman has a little over 1200 miles on it. The valves just started to make a very slight ticking noise after my last oil change. I was running amsoil 0w-40 but swithched over to Shell rotella 5w-40 synthetic. I went to the shell because I use it in my Goldwing and like how the bike shifts. I also have run it in both my son's Recon Es without any problems. I like having all the machines on the same diet of oil. It makes maintance easy and the rotella is always available at Walmarts for under $17 a gallon. Anyhow, The dealer said its rare to need a valve adjustment under a 1000 miles, ( this place sells alot of honda atvs!!) any thoughts???
