Unfathomable noise

[JWScarab]

I agree 100%. Its the gas tank vent tube or "rattle tube" as i call it. Id almost lay money on it. Been there done that.

I know you said all your heat shields were tight.....take them off, go for a ride and see if it still does it.

Does the noise go with the RPMs? Does it get faster over 2500 RPM?

It could be many many things....could be a loose spring on a valve, could be a pushrod bleeding over....etc. etc...

Since WE can't hear the noise, you say it 'sounds' like sheet metal....take your heat shields OFF-even though you say they are tight and go for a ride.....

Leave the clothespin in until you find the noise.....

Regarding the rear exhaust bracket. I believe someone mentioned that it could be loose. The exhaust bracket for my V&H was tight but it had a crack the entire length of the bracket at the weld. Had it re-welded and took care of the sheet metal rattling noise.

I dropped a throttle cable brass end keeper down the handle bars once and it drove me crazy for a week until I got it out.

Not yet. Very frustrating. The bike actually has so few parts! It definitely sounds like it's coming from the front when you are sitting on the bike.

I had an odd noise in the front of the Pit...turned out to be a broke compensator spring. Its hard to pinpoint noises sometimes. You'll have to go over it with a fine tooth comb until ya find the bugger.....just let everyone know what ya figure out.

Where is the compensator spring?

Where is the compensator spring?

Its behind the compensator which is in front of the front drive gear on the motor. Gotta pull the primary cover to access.

Ok I will when i get home

Here's the front 2

That was a really great description huh? lol. Its actually part of the compensator itself. When it breaks, things still work, but it can make some weird noises. I replaced the whole assembly and no more noises....well at least not the "old" noises.

Thanks for the suggestion

 

[zenbiker]

I will certainly look into the compensator spring because that is what the noise most most sounds like... A broken spring.
Thank you much.

Possible gas tank vent tube rattling, has happened to many on here...

It does sound like it is coming from the gas tank
