Just went through posts back to October. I know somebody said they waxed the drive belt to make it stop squeaking. I gotta wise ass neighbor who rides a Hurley. He keeps asking what's wrong with my S40. Sounds like I ran over a rat. Its the belt ... I think.
First, what do I wax ... the side of the belt ... the teeth ... the whole thing?
Second, what kind of wax?
And finally, what's this about grinding off some part of the teeth? That sounds like you might solve the squeak and weaken the belt.

In search of a more melodius thump ...

if that don't work for you, then it's rubbing on the front pulley.

could be from having the spacers on backwards on the wheel.

but you may have to resort to "lubing" the belt
or grinding the teeth a bit

when you grind it, you don't grind on the main part of the belt, just the teeth, no strength in the teeth.

I can't believe how loud a little squeak can get at different temperatures,....mostly cold temps.
But mine has never lasted more than a 1/2 mile down the road. So I've never done anything to it,...doesn't bother at all.
But then, I don't have none of them thar Harley riders to deal w/ either !

+1    on grinding the sides of the belt, only on the side of the teeth, at a low angle of 5-7^o so the edge of the teeth don't rub on the pulley washers any more, making that durn squeak sound.

It is permanent, it requires no maintenance and it only squeaks when you run some in the rain and are drying out from that.

I thought that silicone spray might be used, so thanks for that confirmation. My tread mill requires silicone spray to lube its big rubber belt.

As for the other solutions, as in waxing or grinding, I appreciate alternatives. I do believe I need to check the rear wheel alignment, as was suggested. I do not have any way to jack up the bike, so I will probably have to have the dealer do it (sigh). I can do simple things, but I am not much of a wrench head. Ergo, I don't have tools, like a bike lift. In my old Honda days (CB 100, 350) I was able to set my own valve clearances!

I bought this bike used, with 1200 miles on it. Some lady had owned it, and, as it is with all used vehicles, I have no idea what she may have done to it. It does run well, but the tranny locks up a bit occasionally. In those instances, I let the clutch out slowly until I hear the transmission CLACK. Then I can use the shifter again. This could simply be a characteristic of a machine designed in the 1970's. The battery apparently ran completely dry, and I cannot tell how much fluid is in it because the battery sight glass is opaque ... not clear enough to see a fluid level. Dealer checked out the charging and put in a new battery ... like they should have done before they sold it to me.

Got to change the oil today (every 1500 miles). I use Rotella, as recommended on this forum, but let's don't get into that discussion again!

Thanks to all.

Silicon spray worked like a charm! Will need to repeat at various intervals and after rain, but that's not a problem.

J2,    out in the future when your can of silicone spray runs dry and you look lustfully at your 4 1/2" grinder for a more permanent no-return squeak fix, post again for details.
