Looks just like the APE manual adjusters. Did your cam chain ever get loud/louder after dropping to the closed throttle position from HIGH RPM's? If so, that would indicate an issue with the adjuster staying engaged in a stripped gear notch, which is the only issue I've ever heard of with ours. (non-hydraulic) Like anything else though, If you like the idea of "swapping it out" for a manual adjuster, for peace of mind...that's cool. Like "RC" mentioned, as long as it's done correctly, and not too tight, it's a upgrade/modification that's reasonable IMO. Keep us posted on what, if any, problems you find/see with your old one when you remove it. So Shakey, Is there a tool, or procedure that keeps the tension on the chain while swapping it out, to prevent it from "jumping time", or is that not an issue?
