Too much noise, is it from Tupperware?

Hi all, I seem to notice too much noise from my LT. It is a mixture of tupperware and engine noise. Anybody have an idea on how to minimize this? I know my girl is old(1999), but this noise makes riding a torture, not fun.

Thanks in advance Gents.

Re: Too much noise, is it from Tupperware?

Hmmm...
Tupperware... I guess the only thing would be to take it all apart.
Make sure that the fasteners are there, replace all the rubber mounted ones (I'm doing it on mine) and put the ones that are missing.
There might be some broken tabs on the fairing, not sure how to fix that, maybe using some foam tape to minimize noise?

Regarding the engine. Have you adjusted the valves? Is your timing chain ok? That could get noise.

Also, your rear brake disk probably is making noises. I've read elsewhere a fix using gasket maker to minimize the noise. Mine just started doing that, I'll be using rubber hoses on the screws to minimize the noise. Or something like that.

... you got yourself a fun project. ...

Re: Too much noise, is it from Tupperware?

A fair amount will be engine, however a couple tupperware things to check are:
  • Where the lower and upper cowling meet
  • at the front, the lower cover could be contacting the cooling system hose
  • Try raising and lowering your windshiled (to see if there is a difference between when it is in contact with the bumpers and not). My z-Technik must be tuned like a bell to the engine vibration at idle, if I raise it off the bumpers very little noise but fully lowered it gets louder and louder the longer it sets - it's like some sort of sonic weapon!
  • Inside the tupperware there may be hoses, wires, and throttle cables in contact with the tupperware. I have also put foam tape along any point where the bracket support sits inside of a dished out area of tupperware.
  • Make sure no screws are missing.
  • Check for damage to the engine protection bars - this might be causing the covers to not line up where they need to causing a rattle. These are heavy bikes and if it has ever been laid over on it's side, even while not moving, it's possible that something is a little tweaked in there.
  • Check the exhaust system, there is a history of cracks at the welds and or the header bolts might be loose or broken.

That should keep you busy for a couple hours, if I think of anything else I will add to the list.

I found my 99LT motor to be pretty quiet but it got loud after about 5,000 rpm. The only part of the tupperware that made noise was the radio cover. I hope you can solve the issue so you can enjoy your ride.

Re: Too much noise, is it from Tupperware?

Between the top and bottom front tupperware, on the outer side where they meet at a point (front), I place a narrow strip of foam to separate them. That has solved a very loud rattle for me.

HTH,

Re: Too much noise, is it from Tupperware?

Hi, finally I lifted the bike, rolled the wheels and guess what???

The final drive bearing had a light hauling noise. Removed the fd oil to find some fine metal flakes powder on the magnetic plug. Later opened the fd and noticed that the big bearing balls cage was blued out(heated) at two points 1 inch long.
From this point I'm starting a new thread "FD problem".

Get a FD drive off eBay from a reputable vendor.
and be happy... the FDs are supposed to be serviceable... or be happy.
