Title: More belt convo.....
Post by raydawg on 05/18/16 at 20:19:46

My belt broke clean across if you recall at about 12,000 miles.
I believe it might have been attributed to trying too many concoctions on it, to get it to quite down.
I believe any kind of lubricant contributes to premature weakening.
I think the noise is mostly associated with a unbalanced belt....
By this I mean if you have more belt or distance (teeth) on the top, from where it leaves the rear pulley, to the front pulley, than from where it leaves the front pulley to the rear.....
Then you will get a noise as the belt will load up that "slack", be it ever so slight, at the front pulley on top where it enters the front pulley.
It will try to dissipate this preloading by moving quickly from side to side, creating a chirp, or push on the pulley teeth, trying to ride up on it like it wants to "push out" and that creates the whine.
I notice, as others have spoken to, weather, temp, humidity, etc, plays a factor, but when the belt is just right, you will notice a nice humming.

I believe the best thing is to just keep your belt and pulleys clean, by brushing them as you do your teeth in your mouth, often, but not twice a day ;D

The belt Dave provided for me is working great. I tune mine by ear, once when the weather warms, once when it cools, and just ignore any noise between ;)

Also I think when you change the diameter of your rear wheel, the calibration Suzuki used in trying to get the best harmonic balance between sprocket and pulley is lost to some degree....

Anybody care to address my theory or assessment?

It's just a wild azz guess ;D

You think Suzuki spent ANY R&D money on the harmonics of this bike? :-? ;D

That is funny, ironically......BUT, look how long this lil' guy has been in production.
It must be a money maker.
Yes, it is primitive in technology and nature, HOWEVER....
I think the biggest factor of keeping this an active product is that its an entry level motorcycle for many.
And as folk get the CC disease from riding, the next logical step in the illness is up.
This is where it behooves Suzuki to make a product that snags loyalty.....
First impressions can be extremely hard to overcome.
Would you agree?

Raydawg you have hit the nail squarely on the head. Suzuki see this as an entry level motorcycle and nothing more. That's why they have never bothered addressing the camchain tensioner problem - it is probably on its second or third owner before it becomes an issue and in a lot of cases it doesn't become a problem for many years if the bike doesn't doesn't get used much! However, having said that, you can go on any other dedicated motorcycle forum and you will find that they all have their foibles! I thought the Suzuki GS500 was the most bullet proof motorcycle ever made (well mine was) until I went onto the forum!.
