Sounds like you have a loose connection to the temp sending unit, it's on the right side of the engine, kinda below the intake manifold.
And you're losing vacuum to the fuel pump, prolly a loose hose clamp or a cracked hose end. put new fuel and vacuum lines, with new T's or Y's.
You've had enough heat and vibration to loosen a lot of stuff, so check it all out.

If your battery terminals aren't periodically cleaned, and the battery trickle charged regularly, you aren't secure with electric starting as your only option.

Excellent, excellent.
You have wrestled with the horns of a dilemma, and dashed the beast to the ground.
You are indeed an evil genius.
For improved induction on your scoop, remove the louvres on the fan shroud, and fit a four inch stainless steel kitchen strainer to scoop. The best ones are at The Family Dollar store, and they only cost a dollar.
You'll see how it works when you get one, convex mounting looks awesome, and concave, it looks like it would suck in a small dog.
A utility knife clears the opening easily with a roofer's hook blade.
Then hot glue or epoxy it to the area it fits best.
I used a four inch black plastic roofing gutter elbow from Lowe's that I cut two scoops from.
At least I think it improves induction, when you hold your hand it there, you really feel the cool air drawing in. Maybe yours already does that, but I wanted to remove the louvres, they sure seem to be in the way.

Brilliant detective work, Doctor Watson, Holmes will be proud when he learns of your development.
I'm all for it, I have a recalcitrant Znen that defies all regulation, I shall employ your procedure at once.

Too much exhaust, not enough back pressure. Change the Y's, the stock ones have too small ID. I'm running a 40 pilot with a 125 main, 42mm filter stuck in the airbox, and stock exhaust at 75 miles an hour at 5,000 feet elevation with 6,000 RPMs from 12/16 sliders in the CVT.

We will repair our scooters in the sea, on the beaches, on the roads, across the fields, and every day, and every night, but we will never, never surrender.
Jolly good show, Tianna, splendid!
Yeah, just do the bigger pilot jet if you need to, the main jet is prolly good. One thing at a time.
How's it run with the lowered needle?

You're getting too much air for that 115 main jet, and not enough fuel through the pilot jet.
The pilot jet should be a 38 or a 40 with the free flow air filter, that will help the low end bog. If you didn't change it then it's either a 32 or a 35.
Try wrapping a cloth around the filter to slow down the air and see if that doesn't balance out your air fuel ratio.
If it does, you can prolly just go back to the airbox and call it good.

Excellent, excellent.
But you need to wrap this work up, and get started on that carburetor. It probably has a 35 pilot with a 105 main jet, or maybe a 108, or a 110. You just don't know til you open it.
What you want is a 115, big old stream of fuel, gushing in there at WOT, and maybe a 38 pilot jet. It'll bring up the power.
Just drain the fuel bowl, disconnect the hose, the fuel inlet hose, and some vacuum lines if they get in the way. Loosen the clamps, work the carb loose, flip it over and use your best screwdriver to take off the fuel bowl, unscrew the jets, see what you've got and upjet accordingly.

Ya know, Smorks, I just did the same thing, but I kinda like it.
I tried the 12 and 14 gram slider combo in the stock variator, and it was too high in RPMs annd kinda dudley, so I went with the 16 and 12 combo, and it started out fine, but at 45 miles an hour the RPMs dropped from 5500 to 4000 and it was like finding a whole new overdrive in the transmission. It powers up fine, but there's a definite step that you can feel after you reach a certain speed.
I haven't tried it for top end yet, but it seems like it will do great.
I also put in a new 871 22 belt, even though the 856 23 was just fine after 5,000 miles.
So, I don't know if it's the long skinny belt, or the slider combo, but I dig it so far, I'll let ya know how fast it goes tomorrow.

It's prolly a long case with those 12 inch wheels, so look for 10 bolts. They're different sizes, so punch holes in a piece of cardboard and stick the bolts in the same pattern they are on the cover.

That's awesome that you got all those radiators. It ain't gonna overheat.
Sounds like the belt's too big, maybe an 872 22 30 would work.

Is there anything cooler than a scooter in a box?
No, that's it, that's the coolest.

Yeah, you go through the square opening in the center, but now you pulled the whole sheboing off, and yer scooter's engine is sittin' there topless.
Get that wrench or socket on the two bolts on the valve cover and open it up. The cover is kinda tight aginst the frame, but once it's off there's another 2 inches of clearance. You can get in there as long as your not wearing a catcher's mitt.
Check the vale clearance, come on, check it.
Oh, and if you do the exhaust, look out for a big splooge of oil to come out when you open the cover, if it gets in your mouth, just spit it out and rinse with beer.

Have you taken the battery cover off yet? Two screws hold it on at the rear. Lift and separate, cross over to a better figure.
See the carb? All those hoses? The valve cover? Radiator cap?
Wiith the valve cover off, you can get your feeler guage and your wrenches in from the rear. You prolly won't even need to adjust it, just check to make sure it's at .004 with the feeler guage. If it goes in the gap, and don't flop around, yer in like Flynn.
You're gonna love the exhaust valve, when you're upside down. That's the one that will be closed up.

Pick a spot above the valve cover bolts and cut a hole big enough to stick a scocket on an extension down onto the bolt. One on the left, and one on the right.
Or cut the middle out of the battery compartment. You'll need a swivel on the socket.
