Hi All,

New to the forum. Looking for some advice. I recently purchased an '83 Magna with about 22k miles on it.

The bike is in superb condition as far as I can tell.

The issue I'm having is when I get between 4.5 - 5k rpms the bike starts making what can best be described as a "screeching" noise which differs from the normal whir while accelerating. The screech occurs while moving or stationary.

It sounds like perhaps something is rubbing/rattling when it hits the right frequency.

Anyone have any similar experiences and thoughts on what it could be?

Thanks for the help.

Update. I've been tightening up everything I can find. I haven't found the source yet. My fear is that it may be engine internal. I'll keep tightening and see if it goes away.

I also don't notice when dropping through the rpms. Only when i'm accelerating or holding the throttle steady at those rpms.

Check your air intake system.

Try it with the air filter out once.

Is there any difference if you hold the clutch in......in gear or in neutral ??

High pitched air leak?...spray some starting fluid, carefully, around the air intake boots. Exhaust joints secure and sealed?
