Bad poly locks? Is this common (2001 Recon)
Hey guys, I have my old trusty 2001 Recon with a metric crap ton of hours on it. when I say this thing is old and beat, I mean it's a modern engineering marvel that it still runs at all.
It actually runs half decent, but I have been having one slight issue with it. I start to hear the valve train ticking away louder than normal, and the bike feels kind of sloppy at the bottom of its power range after 1st gear (going into second, third, fourth...the bottom of the gear range feels sloppier as you go up until you get the RPM's up). AT first I figured the lack of power at the bottom of the gear range was a clutch issue, as the bike is ancient and I'm sure it needs some serious attention in other areas. when I adjusted the valves though, the bike felt WAY better and didn't have the chattery/sluggish feeling at the bottom of the gears. It felt crisp and responsive.
The issue is, after only a few hours I start hearing noise again and the sluggishness returns. I've tried adjusting the valves 3 or 4 times and the same thing happens each time; fine for a little while and then it goes back to the way it was before. It never gets any worse, just doesn't stay as quiet in the valve train or as responsive feeling in the throttle.
I'm thinking it may just be the poly locks are worn out in the rocker and preventing them from holding an adjustment? I know that's a thing on solid roller cam smallblock chevys but is this something you guys have seen on ATV's or am I barking up the wrong tree?
