I need to pick everyone brain a bit!
On our last ride i noticed my valves chattering a good bit. And i know its a honda so some tick is normal but this was more then normal. Being that over the winter i put the new valves in i figured it was the new valves seating in and just a quick adjustment would clear everything up. So i took everything apart and checked the clearance on all 4 valve adjusters. 3 were tight. Like .001 tight. And one was loose. Like .008 loose. Which i though was kinda weird to start with. But i have taken it on 3 good full day rides and im not afraid of the rev limiter one bit so i adjusted them to spec. I got the intake to adjust perfect and i struggled with the exhaust alot more than normal.(I adjust valves alot) everytime i would get them perfect nice drag on feeler gauge i would torque the nuts after snugging them and they would be loose again even though the adjuster screw didnt move. I did finally get them close enough to try and put it all back togeather and took for a test ride. Sounded almost the same as before.
After some thinking and research i decided the adjuster screw and nuts needed to be replaced. So i ordered some oem ones off rockymountainatv.
Got them and installed. I was able to adjust them alot easier again. So i though i was good to go. I adjusted all of the valves again and i did my normal test with my finger on the end of the tappet arm to see if they made any noise and all but one were silent. The left exhaust valve taps like its loose but with my feeler gauge says its perfect.(never had this happen before). Going exhaust valve to exhaust valve they both have identical amount of drag on the gauge.
Thought well maybe the oil will get in there and quiet it down. And i was close to being right. If i start it cold and let it idle they chatter like crazy. If i rev it up a few times or when im riding its completely quiet. That being said it struck a cord in by brain and i though oil pump! Figuring it was getting weak. Being that its stock and this engine had been rarely maintained before i got it i did the oil pump check outlined in the fsm. And it passed the test perfect. Took the 10mm bolt out below the 2 oil lines and zero oil came out. Not a single drop even. So now i am stumped. Should i even worry since its quiet when riding or if i even just rev it once at idle its quiet and sounds perfect. Im on the fence. Sorry for the long post but throw your opinions out there please. Thanks!
