One more try for help

I Ran across this video today comparing an aftermarket to OEM Carb on Suzuki Vinson, thought it might generate some interest, it is quite long but informative.
 

So I've got a Hisun 550 that I was doing some work on that required removing the CVT and it's housing. Upon attempting to reinstall the clutch, sheaves, etc, I found that the belt no longer fits - it's far too wide. None of the parts have been replaced, they're all OEM. Exactly the same parts as what I took off a few weeks ago.
To be more specific, my belt is 1.25in wide, but the gap between the clutch and the primary sheave is only 7/8in wide. I'll include a few photos to explain.
Has anyone ever experienced such a bizarre problem? Any help at all would be appreciated, I've been stuck on this for a month. I'm open to just about any suggestion.

I’m looking for a top end kit for a Yamaha. I would like to see how well the engine runs before spending $6-$7 hundred on oem. Niche has complete kits from $1-$2 hundred.  Anyone have experience with Niche or similar Chinese companies? 

This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
 
My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.

Hello there
I'm having a problem finding a quality carburetor for a 1993 Suzuki Quad Runner lt-f 250 2x4. I find a lot that have 3-4 star ratings. And all so far don't have the right throttle Cable inlet at the top. The last one I got 4 star on Amazon has a threaded cable sheath rest that could be partially drilled to work. I would prefer to get one I don't have to modify. Any recommendations are greatly appreciated!
