My Honda service manual says .005 but .004 is fine... Just make real sure you DO NOT start the bike before attempting to adjust your valves push it where you will be working on it. once you adjust them and run the bike you got to wait a few hours before making any other valve adjustments. warm will give you a false reading.

I think so mine is a little noisey too and I've got the same quad as u just a year newer. check your decompression lever when it's running that may need adjusting. it's on top of the head on the right side if your sitting on the quad.

Hondas always have a bit of excessive motor noise. I can hear my cams and everything working, everything is in spec and pretty.

You need to check and see if that oil is for Motorcycles bro. regular oil won't work you will destroy the clutches. motorcycle oil has friction modifiers in it just for wet clutches. if it's car oil drain it out do not ride that quad another foot!

I've been running mobil 1 10w40

Hate to dredge up an old thread but I need to ask and I did a search and this was the only thread I found mentioning Valve train noise. I have a '97 4trax 300. I changed the oil when I got it with the Honda oil and adjusted the valves. It still has some top end noise. Two weeks ago I was at my BIL's place and he has an almost zero mile '90 4trax 300 and it's super quiet. It just makes me think I have something wrong. Does a worn timing chain make noise?
