Motorcycle engine cutting out when lights are on?

Just recently my old motorcycle (Honda Dream Exces 100, probably bought by my pops back in 2002) would shut off during neutral state when my headlights are on, except the signal and brake lights. Then it wouldn't start anymore. I have to turn off the lights to make it start. Then often when headlights' turned off, the engine starts but it was like cutting out and i noticed that the engine goes back to normal after accelerating it (in neutral state) for maybe 30 secs or a minute. Can someone help me, advise me what to do. Please.

Why is my motorcycle not producing the power that it should?

My 1985 Honda Magna v30 runs fine(sounds normal) but I have a hard time reving it above 9,000rpm with full throttle which it should hit red line at 11,500rpm… I'm cleaning the carbs currently. Sometimes it has a hard time starting-eventhough I can hear it combusting. It should be able to hit 110mph with ease but it has a hard time getting to 55mph right now.
I have already ordered
-new air filter (it was thick black in the inside)
-oil filter
-?(this part is for you to answer)
what should I get, repair, clean, or inspect

How hard would it be to ride a motorcycle when I've never rode a bicycle in my life?

So my friend recently offered me to ride his Honda CBR250RR the next time I see him. But, the thing is I've never rode on anything with two wheels before. Not a scooter or a bicycle. The only experience I've had with anything similar is on my ATV. Would it be harder to ride a motorcycle? I've heard that going fast is much more stable than going slow. Any other tips from you riders out there? If so, thank you very much!

Added (1). The bike is a project bike so it's not like it's too bad if I drop it. My friend himself has even said that it's fine if I drop it. I'm helping him fix it anyways. We're also going to be on a private road so traffic obviously isn't an issue. I'm a beginner that's simply practicing, not riding on the road or anything dumb such as that.

Trying to buy a motorcycle. 2 bikes close by on Craigslist. Which should I buy? Which is better?

1st for $600 a 2005 Xtreme Montana 250.
"2005 Xtreme Montana 250. See pics. Runs good. Clean, low miles. See pics"
It's a really nice looking bike, I'm just scared it won't last.

Secondly for $700 a 1982 Honda CM250
"Nice beginner bike, easy to ride. Great condition. Runs perfect, starts up easily everytime with electric start.inspected, everything is good and works. A great reliable bike. Only 4800 original miles! Always stored in garage."

If I buy the black one (the 1st bike) I'll have $100 left over but if I buy the one, it might cost me a little gas money to go pick it up. I have an under the table job and don't make much.

Do I need a new battery for my motorcycle?

I ride a 2012 Honda CBR250 and I just bought it 3 months ago. Although I ride it 3 times a week the battery ended up dying on me. I recently got a jump and it starts up fine now. Do I still need to take it to a motorcycle shop and buy a new battery?

Problem with starting my honda bike?

Hi. I have a honda cg125. About a month back it started giving problems to start (cold start that is in morning) Before i would just press the start button and it would start flawlessly. Now when i press the start button it starts then cuts out. Start again idles for a while then cuts out. I then have to end up using the choke. The problem is not the battery. Replaced spark plug, brand new ngk iridium. I have absolutely no idea what this problem is. I took it to the honda official service shop, they serviced the carb but i still have the problem. Please help!

Also i hear a whistling sound when i start it i.e is cold start i'm talking about. During the day it rides perfect.

Help.

Added (1). Yes i know but before i didn't have to use the choke at all. The engine could have been really cold and one touch of the button it would start. I want it to go back the way it was.

What scooter is best for commuting in London on daily basis? 125cc vs 300cc?

I like the Honda PCX 125 and also the Honda Forza 300. I do not know which one to buy.

I wonder if 125cc is enough or if I should go for the 300cc.

New or 2nd hand?

I also have seen the Honda Forza 125 and I wonder if it is worth it.

The PCX seems to be very good value for money (maintenance and running costs), however it is small size in comparison with the Forza 300 (obviously at a higher cost).

Any suggestions? What scooter is best for commuting in London on daily basis 125cc vs 300cc - 1
