Killing the vibration......how?
« on: October 08, 2008, 10:08:14 PM »
Among other things I broke this tach and another smaller and cheaper one while at Bonneville this year. I have another tach and am hesitant about putting it on the bike the same way as before as I amalmost certain there will be a repeat of what happened at Bonneville.

So my question is how has everyone mounted there tachs before in high vibration areas? My bike is a Harley ( VIBRATION! ) and it is a rigid chassis ( MORE VIBRATION ) and the motor is rigid mounted ( EVEN MORE VIBRATION ) so can you please help?

Thanks,
Scott

I recommend using some pieces of SHOCKtec Gel from Kemmler Products in Mooresville, NC.

SHOCKtec Gel is nothing short of amazing. It's used by dozens of Nextel Cup drivers, and also in gloves for jackhammer operators, on high-end motorcycle seats, and in law enforcement, under bulletproof vests to minimize bruising. Here's the company's site:

You can reach Tom Pierce at Kemmler Products at (888) 411-3884. He may offer to send you some samples. Tom is a good guy. Please say hi to him for me.

Hey Scott,

I have had great luck with vibration isolators from McMaster - www.mcmaster.com

do a search for - High-Temperature Vibration-Damping Sandwich Mounts - page 1351

Maybe use two small ones in your case

Kent - We did have this conversation, but Summit sent me another tach so I am kinda in the same boat. I didn't know the Harley liner was there........I will come and check it out.

I call you about the signal tomorrow and get specifics.

Scott, everything that can be killed with vibration on an HD is rubber mounted.... or suspended somehow. :roll: 
You may need to try several things to get something that is soft enough to absorb the vibration, but tough enough to keep the tach on the scooter.
Good to see ya on the salt  8-)

if your harley shakes -vibrates--if things fall off and metal cracks you need to balance your motor--if you have then you need to find someone else to do it again right--  sometimes it can be the way the motor is mounted especially in an aftermarket frame ---anyone that wants to feel smooth harleys should ride mine and sheris bikes (hers is a 500 single the worst for vibrations )  our bikes are balanced by dave bozzie  ----just some thoughts   willie buchta

There is a book, "How to stop a Harley from vibrating".

It's in the section of the library with:

"Understanding how the Female Mind Works"
"French War Victories"
"I didn't do it - OJ Simpson"
"How to machine Unobtainum"

Just kidding.   :evil:

I had an AMF Sportster years ago that vibrated the fillings out of teeth.
