there are 2 allen head cap screws at the fromt of the seat underneath the side covers that hold it in place

when you replaced clutch plates did it compress up when you fitted the end plate with springs , also did you soak the fiber plates for a couple of hrs before fitting ! on the end clutch plate is there a centre nut and screw that you can adjust the free play and did you reset this ?

Your clutch has worn out or exceeded the useful life and will need to be replaced, this isn't a hard repair if you have basic skills and tools. The repair should begin with Yamaha repair manual then read the section for clutch and you can judge for yourself if you can do it, if you do take lots of pix of everything you touch or remove as this will be of great value upon reassembly. If this is your first time repairing your scoot it will make you proud you did it yourself. Good Luck

Adding too much oil to any engine can cause leakage and potentially damage.

1.100 rpm.

Two allen bolts under the seat - towards the back of it, one either side, then simply lift off. Don't lose the little washers.

I may need a bit more clarification, but I am assuming the lever is 'spongy'?
The simplist thing to do first is to tie the front brake lever back (ie make it stay on) using a zip tie. Leave this overnight/24 hours and it will allow the trapped air to rise.
Failing this, you can bleed the brake in reverse. Get a large syringe (ebay/chemist) and some pipe that fits over the bleed nipple and the syringe. Remove the master cylinder cover and **** out (use the syringe) the brake fluid. Now fill the syringe with fresh brake fluid and connect to the bleed nipple on the caliper. Open the bleed nipple and slowly push the syringe in, to force the fluid up to the reservoir. Be careful that the fluid doesent come out of the reservoir and splash on your paint work. Lock the bleed nipple up whilst still slowly forcing the fluid in. This normally works.

Okay....I think your bike may have a vacuum operated fuel petcock.....which is the fuel valve on the bottom of the tank. It shuts the fuel off automatically when the engine stops and the hose from the intake to the side of the petcock loses vacuum.
So when you restart the bike the petcock is closed till the engine starts...which is okay because there is a small amount of fuel in the carb.........until you run out of gas....then the engine quits and the carb is empty.
To handle this situation, typically there is a prime position on the petcock that allows flow without vacuum to "prime" the empty carb......usually marked as PRI on the petcock,
So rotate the lever on the petcocck to prime....wait a couple minutes....get the bike started and set the petcock back to the normal setting....don't leave it on PRIME as fuel may flow overflowing the carb.

Your bike should have a cable driven speedometer. Look at the left side of front wheel...wheel axle is, you will see the speedometer cable attached. make sure that end is securely tightened, if it has come off, the internal cable may have slipped out. If its okay....now go under the speedometer housing and check the nut on the cable at that end...make sure its secure. Chances are it loosened off so cable was no longer engages into speedometer.
Other possibility...cable inside the outer sheath broke. A new cable is around $20 Cdn.

If you want to but why would you want to?

you will need to remove ur seat in order to get to the bolt or clip down that holds the rear of the petrol tank to frame.make sure the fuel tap is off & remove the fuel line going from tank to carburator then remove tank & empty the old gas out.there should also be a drain bung/bolt on bottom of ur carburator bowl,undo this let all gas empty out,then re-tighten & then reverse steps to put tank back on.Fill with fresh gas try start,check for any leaks & should be good to go!

Not much info to go on but could be a dud / flat battery. Once engine is running will run all accessories.

Drain or remove and clean the float bowl on the carb. Chances are the bowl has a bunch of water in from condensation in the gas tank.

yes it should be in the same genral spec range
