Suggestions on Squeak location

[NUKNUK]

Bike makes a distinct squeaking noise somewhere below battery box and towards the rear near the exhaust tips during decceleration and when I'm not on the throttle. Does not squeak at all when I'm on the throttle or pull the clutch lever. I'm going to place a thin rubber pad between the exhaust bracket and frame bracket, even though I have them tightened down so much that I don't see how this could be it. Could this squeak be coming from the clutch pushrod or somewhere from the tranny?

Check your top motor mount

It's definitely not the motor mounts.

The dreaded belt squeak? Rub a bar of soap on the inner and outer edge of the belt and see what happens.....

I kind of ruled that out just because I figured if it was the belt, would'nt it squeak at all times?......

Nevermind, I just read the belt chirp thread. I'll go ahead and treat it as a belt issue and hopefully that's the culprit and I can go ahead and fix it.

Check your fender stay bolts. Mine squeaked like a mother when one was loose.

Will do. I had the bike torn down over the winter to just frame, motor, and tranny. I finished putting it all back together around 4th of july and went over every bolt with a torque wrench and proper loctite. So I'm pretty sure all the bolts should be tightened down to spec since I'm a little ocd.

Did you realign the motor, trans and rear pulley when you reassembled? I had the nasty chirp before I tore the Pit down. I realigned everything, made sure the belt was true forwards and backwards and haven't heard a sound since. And I can understand the ocd!!

If all else fails to fix it pull the clutch throw out rod check it for scouring and out of round. It should be well lubed as well.

That's exactly what I've been thinking is causing the noise (I was calling it the clutch pushrod). There's not much info in the manual on how to do it. Can I leave the sprocket cover plate and clutch cable attached, and just unscrew the pushrod cover from the cover plate to remove the clutch pushrod?

They cut the belt pulley too close so ALL BD bikes squeak. Buy some teflon spray and spray it EVERY time you ride...

So......... and???

I feel its in my stock exhaust. I just order some Vance and Hines pipes. So we shall see.

Periodically, Ill roll down the street and shut the bike off and listen to to it. Just a thought.

Is a squeak an electrical thing???

 

[Hirter6Pack]

I think we've been here before if it doesn't squeak when on the throttle -stay on the throttle. Problem solved.

Did you check your heat shield clamps? Smack the shields with the palm of your hand and see if they sqeek. Just a thought.
