I have a 98 foreman that I bought used. Guy had done a top end rebuild, said ticking was from valves that needed adjusted after so many hours of riding. I rode it around multiple times, set and set and set valve lash with little to no change in the ticking. Thought maybe the timing...
Hey atv techs!
Just replaced the head on my trx450es, which came refurbished new valves, springs, etc and supposedly adjusted. Motor seems to run great, except for this loud ticking. Should I be checking valve clearance first, or does this sound like something else?
