Technically, a Slingshot isn’t a motorcycle either...
look up the definition of trike.....
Whining noise at 50mph

That's one of the questions I am asked often - is it a car or a motorcycle? NH considers it a motorcycle but I think that's just for insurance purposes. I just call it a buggy.
in PA it’s classified as an autocycle (But follow the motorcycle rules with a motorcycle license plate and no motorcycle drivers license)...mainly because of the steering wheel and the side by side seats...

Here's what I use. Just a quick spray, no more squeak/squeal.

Thought that looked familiar...

If adjustment of the belt is required, simply go to YouTube & type “slingshot belt adjustment” into the search box. The Sam Owens videos are very thorough...
Tripod ,that all you got ! lmao

Yep. I’m pretty much worthless...

when I’m coming to a stop after letting off the gas (Coasting) I hear a whine that sounds like a jet engine slowing down...not real loud but it’s there..

Good to have you back...you ALWAYS find the answers befor emost of us can find the search button.

Just call it a sport trike.
Let everyone else argue what it is or is not...

Get that damn lube off of there. Wash belt (both sides; inside & outside) thoroughly & meticulously with warm soapy water & a nylon brush. Then rinse belt with clean water.
Also verify belt is positioned properly on the pulley. (See my pic on previous page)
-
I didn't wash my belt. Just sprayed on belt dressing. Quiet now....
-
I'm confused, I thought I was supposed to spray it with dry lube (and it did seem to work for a while.) I'll give it another good scrub.
You proved with the lube (belt dressing) that the belt was indeed the whining noise source. The belt does not require lube (dressing) & is, in fact, detrimental as it can attract more contaminants. The belt merely needs to be kept clean AND ADJUSTED PROPERLY. You’ve never posted if it’s aligned in the pulley properly & at the proper tension (up & down travel) adjustment. If the belt is rubbing against either side of the pulley, that will also cause noise.

From a belt manufacturer:
You can ignore the statements about having to replace the belt. They are discussing conventional serpentine belts for cars. However, the other points apply.

Sorry for the poor quality, this was taken at like 10 at night and my garage has no lights.

Doesn't look like the belt is aligned properly, the gap on the right side should be about that size on the left (drivers side). At least thats how I understand it.
-
Posted this on previous page but again, belt should be aligned closer to LEFT side. From the service manual, see item #6 below & pic of proper alignment:
-
The service manual has the alignment that way for a reason. My theory is that under torque, the belt shifts slightly to the right (outboard) - so if belt is already over to the right, then the edge of the belt will rub against the pulley flange, thereby creating noise (& unwanted wear on edge of belt). That would certainly make sense.
If you look at step #8, it confirms this. Don’t want to go TOO far left though, or you’ll get same problem upon deceleration:
