Hi Everyone
I just picked up a 2005 Rancher 350 ES that has 2200 miles on it and runs very well but has a interesting valve train noise. Is it normal for this type of engine to have very loud valve noises? When sitting on the bike you can hear the constant sewing machine tick-tick as the pushrods and valves do their thing. When i rev the engine the sound increases proportionately but it always seems smooth albeit loud. Doesn’t use any oil, power is great, no smoking, just high pitch sewing machine sound from right side of engine.
I asked the original owner if he ever checked the valve clearances and he said it was only done once during the initial service. Is this type of noise normal or am i looking for issues that aren’t there. So many threads on timing chains gone bad, valve seats etc…. The following video shows the sounds its making, if this is normal then that’s great!

BTW, i had a 2007 Foreman 500 before and i don’t remember it sounding like this but maybe that’s a different engine design
Thanks for your help!
Cheers
