Its not to the airbox. That tube goes from the frame to the CVT cover. You can see the tube opening on the front of the CVT cover in the pic I took of it sitting on my seat. The airbox has been removed and this filter was installed on my 20mm carb Although I found out these aren't waterproof like the airbox was and I soooo killed my scoot in a downpour the other day.

I know that tube goes on the cvt you where asking why it was going into the frame.
And yes SCOOTS do not like water and if it gets into the carb it will most likely kill the motor and if it gets onto the electricals it could fry some components as well. Wile

The vent tube usualy has a bracket mounted to the carb that it sits in and holds it to get fresh air

That tube is an intake toube the one that should go on the cover is straight so it has forced air that could be y its heating up to

So can someone help me understand what's causing this noise in the starter. Is it because my fan is gone off the drive pulley/variator? Or is there something wrong with my starter? It was making this sound before the belt broke for about a day.

So no one has ever heard this noise in a starter before? I hate to replace parts if something is wrong with the starter. Just trying to cover all my bases before putting a new belt and fan on her, incase something else is to blame.

It was making this sound before the belt broke for about a day. Nasty sounds there. You need to remove your variator cover and inspect the teeth on the end of the starter bendix and also the end of the starter shaft for damage. It sounds like your bendix is not returning to the disengaged position after you finish cranking it. This is caused by a spring built into the bendix that weakens when it is heated repeatedly. You can get a bendix for about 15$ before shipping and tax if you find problems with it. The toothed face of the variator could also be bent. Rotate the engine by hand to see if it has any wobble causing poor contact with the bendix teeth. Finally the electric starter end bushing bearing that the bendix slides into on your variator cover can be worn enough to cause the bendix teeth and the variator teeth to mesh poorly the bushing is about 4 $ plus shipping.

I'll look around and see if I can notice any worn bushings. If I pull it out at an angle I can get the starter gear assembly out. I checked the teeth on both already. There aren't any bad, missing, or bent. I even held a socket over the tip of the starter gear so it wouldn't fly out and started it with the tranny cover off. It makes the same pinging noise. Would it have anything to do with the missing fan? I have not replaced it just yet.

Remember there is a spring in the bendix that allows it to retract once the engine speed is higher than the bendix speed. In the video it sounded like your bendix is not retracting and staying engaged with the variator drive gear too long. My recommendation is replacing the starter bendix unless you want to take a video of it's operation or supply some pictures etc of the actual part. 15$ is not bad at all.
Highly unlikely but make sure your starter is tight. Two bolts from the passenger side of the bike.
A missing fan will increase the temps inside your variator cover by a good bit. I'd find a replacement or you could have a broken belt issue in the future.

LMAO, passenger side, and btw the fans missing because it already overheated somehow, melted flew off in the casing and destroyed my belt...aka page one of these posts lol :-P I'll b up with some pics and check those starter bolts here soon!

Oh, you are the guy that broke his belt into like 7 pieces! This forum doesn't really advertise what page you are on when compared to others I visit. Considering the state of your belt and fan when they came off I'd be willing to bet your variator starter gear ( the huge one the bendix meshes with) is bent a good bit be a lad and remove it from the bike and put it on a table I'd imagine it's warped a lovely bit and that table will show you the warp.

Yup, that would be me lol. It may be a day or so to get it apart and take a look at the variator. I have to borrow an impact, havent had the extra cash to buy one just yet, but they are sure handy! This scooter's sure given me the run around trying to figure out what went wrong

Just out of curiosity, I've seen that some people cut and modify their CVT covers to make them vent better. What kind of problems would I get into if it rained and got water in it? As of right now my scoot is my only transportation. Rain or shine!

When you open the CVT cover by cutting a hole in it you expose it to the elements of mother nature, Sand rocks sticks insects fingers and all manner of contamination is free to enter at it's convenience. These objects can have only a negative impact in the what should be clean and dry environment of the CVT cover housing void.
If you were to get a good bit of water in your cover you may have issues with rust and aluminum corrosion to varying degrees, ( nonexistent to component damaging) accelerated belt wear, possible slipping components if the water is able to wash oils and greases from their proper locations, etc etc.
No claims are made that any of this actually happens, but who's to say what is possible and not out there on the road.

And I agree 100%. Those were my thoughts exactly. I've just seen several pictures on the internet where people have opened them up so they can breathe. I see if you have the money you can even by them costumly made with vents and openings around the clutch. I just was hoping to find someone who had done this maybe and could inform me of any problems they ran into by doing so.

BLAH!!!! OMG its just one problem after another. I knew it wouldn't be as simple as just a new belt. I haven't bought a fan to put on it yet, but I got the belt on. Even a kevlar belt to boot! Every time I get it running, the variator nut backs off?!?! Is this because of the missing fan? I'm putting it on with my impact like I always have.

You need the fan the kick start pawl the variator any washers and other tidbits to ALL be in place before you tighten that nut down. Not having all the proper components in place can cause the Nut to damage the splines or the splines to damage the threads of the nut, or the nut to not tighten properly and back off, or components to wobble such as your variator drive face. What happens when a variator drive face wobbles? The belt overheats and destroys it's self! Hello Square one.
Get all your parts fan included.. then put it together.
