Cam chain noise

[sprtrx300ex]

Is it normal for the cam chain to make a whining/ decell noise after you rev it? If not what is whining?I believe it started after i messed with the idle and fuel mixture screw.

PLEASE HELP :(

god man i dunno what to tell you there! can you describe the "whining" any better? is it like a turbo diesel type whine or a screaming-late-wife-that-hasnt-had-her-morning-coffee-yet type whine? lol

It is like a high pitch to a low pich whine after every rev. It only lasts like two sec. Sounds kinda like a space ship landing!

hmm.... i don't know if you can tighten the cam chain or not..... best bet would be to un-mess the idle/fuel mixture screw. but im not an engine expert! hey.... our 350 rancher does that also..... it might be normal it sounds kinda kool eh'!
