chuby you my be right about the valve seat idea ,you're aso right abou the Honda 350's not having push rod's the 86' TRX 350 4x4 i have has Hydrolic lifter's no push rod's the valve's are actuated by way of the overhead camshaft lobes not push rod's as are the 2004 model Rancher my brother own's i'v done the valve adjustment's on all the ATV's we've owned so i know the differance between them all to be the same on the engine's on both quad's ! I can remove the sparkplug from a lawn mower stick my finger in plug hole an tell if there isn't any compression at all, and lawn mower engine's have push rod's to open and close the valves, not like Hydrolic lifter's unless it's has a Hydrolic overhead valve engine ! on all the Honda TRX 350 Hydrolic overhead vale engine's on these quad's ! before anyone jump's on my case about this i know this isn't the way to go on compression tect's i'm just saying if there's 0 compression you want feel any pressure even with your finger stuck in the plug hole! And with over 20 + years in the bussiness of small engine repair from service,tune - up and major overhaul i do know a little bit when it come's to any small engine. Even overhead hydrolic valve engine's. motorcycles like honda's from the CB 450cc double overhead cam to the Honda Goldwing 1100cc 4 cylinder's ! And i called the local Honda dealer the last time i adjusted the valves on my 86' TRX350 forman 4WD 4x4 witch has no push rod's but Hydrolic overhead valve's. and my brother's 2004 Honda Rancher 350 fulltime 4WD the Honda Dealer said valve spec.'s were 0.03 intake and 0.04 inch on the 86' and 2004 Honda Rancher 350's are the same. I also Called My local Arctic Cat Daeler and they work on all make quads, they told me my old 86' foreman TRX 350 and the 2004 Honda 350 Rancher are 0.03 intake 0.04 exhaust they're both maual shift tranny's ! I asked about setting them both at 6 and was told on the 350'Honda's were 0.03 inch Intake an 0.04 inch Exhaust we're talking 350's here On the Honda's with Hydrolic valve Lifter's working off the the cam lobes; they told me some of the smaller and larger engine's had a larger gap setting on them ! I asked a bout a 96' Yamaha 350 Wolverine Full time 4WD my brother also own's and was told valve spec.'s for it is 0.04 Inch Intake and 0.06 Exhaust and a 93' Suzuki King Quad 300 4WD that i own are the same as the Honda's 0.03 Intake and 0.04 Exhaust and both the Yamaha and the Suzuki are Manual Shift Tranny's ! I've adjusted the valves on all these ATV's myself and they run as good as new evry since the first valve adjustment's and the last adjustment's i did on them last month with the same result's still running like new ! ........................williebee
