Rubber grommets 9/32" size from Home Depot (available in the specialty drawers that they have for 72 cents each).
Insert into the holes on the three brackets attached to the gas tank. Apply a little spit first as it will help you get the grommet to seat easier along with pressure from your thumb.
Apply a light coating of a lubricant preferably compatible with rubber on the little steel rods that hold the speedometer housing, then add small plastic O-ring washer (also from Home Depot available in the plumbing section or the little specialty drawers in the hardware section) placed between the spring and the grommet, and wah la----no more squeaking noise.
Follow up:
I have put about 1800 miles on the bike since adding the grommets---held out so far. Plan to add the shrink wrapping in combo with the grommets the next time the tank comes off, just for good measure.
I thought this idea looked interesting, so I used it as the basis of my quest to stop the infernal speedo vibration.
I was unable to find 9/32" ID rubber grommets @ Lowe's, so I picked up some 1/4" ID rubber grommets:
I would not recommend these for anyone else, as getting the speedometer mounting studs through them was a struggle....I though I was in danger of cracking the speedo housing! I ended up chamfering the edges of the stud shoulders a tiny bit and lubed things up with silicone grease to get the three studs to cooperate.
To keep the springs from contacting the rubber grommets, I used some nylon washers:
These were a good size to use, I think.
Next, I wanted to keep the springs from ever coming into contact with the studs, so I shoved a short length of 3/16" ID, 9/32" OD clear tubing over the studs. Here is what the tubing looked like before I started cutting:
The tubing was a tight fit, so I softened it by dunking it in boiling water before I shoved each little piece over a stud.
Here is what two of the studs looked like before I put the springs on:
You can see the "stack" consisting of the rubber grommet, the nylon washer, and the short length of tubing.
Then, I put on the OEM springs (they were a tight fit around the tubing, but I sort of "screwed" the springs into place. I topped off each of the three speedometer mounting studs with the OEM cone washer and the OEM nut. On two of the studs, the spring started to coil bind before the cone washer was set against the shoulder of the stud. So, I backed off the nuts that were associated with coil bound springs and double-nutted each stud, using blue Loctite.
If the vibes don't stop now, at least nothing I've done isn't irreversible.
Thanks, pmanntex, wherever you are!
