TubeNet

I have searched the old TubeNet forums and have gotten some great ideas about keeping valve spring noise down on both of my piston horns. Since most of the posts are two years old or more I was wanting to know if there have been any new ideas that have been thought up that would be more permanent and sanitary that coating the springs with vasoline or lanolin. Or is this practice of coating the best thing for the noise? Are there springs that are made solely for being quiet? Any ideas are welcome.

Thanks, Clay

How about this?

I read that heat shrink post when it was written and thought it was a good idea, but I don't think that the ends of my springs are making the noise, because they are touching the actual piston and the bottom cap. My problem occurs in the middle of the spring when it is compressed together. Thank you for the input!

I'd like to try some Kevlar coated platinum springs. Someday.

I had the same problem with a brand new horn that I had bought in March. I tried a couple of things to get rid of the problem including coating the springs with slide grease and stretching the springs a little to incerase the amount of tension. The slide grease got rid of the noise but got all over the pistons and gummed them up .

What finally worked was I just made sure the springs were seated properly in the bottom valve caps when I put them back in . Once I did that there was no more spring rattle.

I hope this helps.

Don't coat your springs with anything. It will mix with your valve oil and really gum up the pistons. Making sure that the springs are properly aligned, getting plastic coated springs (Yamaha makes them), or getting slightly narrower springs would work better.

1st thing.... you have to insure that the springs are square on both ends. In other words, take them out and inspect them to make sure they stand up straight on both ends. If you stretch them, they will tend to bow outward in the center when they are compressed. If the springs aren't square, replace them.

2nd thing.... make sure the springs fit the locator areas in the bottom of the piston and in the bottom cap. If they don't match, get the correct springs.

Springs are cheap and aren't worth spending the time to agonize over.

Anyone had experience with plastic coated springs? Where can I pick some up?

BINGO!!! simple, makes the most sence.
