Honda xr70r dirt bike won't start?

My brothers xr70 randomly stopped working and has been sitting here for a while. I can't seem to get the gas lid to open so I can't see if it has gas or not. I put it in neutral and tried to start it but she doesn't wanna work with me. I'm not really sure what I should try. Suggestions? (NOT GOING TO A ENGINEER BECAUSE I'm TRYING TO SELL HER)

What are primary fluids in a motorcycle?

I asked my friend for a list of DIY motorcycle repairs I can do for my bike. He said transmission, oil change, primary fluid change, etc.

I've managed to find a tutorial on hwo to do all of thse things except for 'primary fluids'. I can't figure out what that even is. He is a harley davidson guy and I know that harleys have something called primary fluids, but when I search primary fluids for my Honda Sabre 1100cc (2007), I don't get any results.

Any ideas? Thanks.

PS I realize I was driivng around without any brake fluid and very low and bad quailty transmission gear oil. Thankfully changed that as of last night.

What equipment do I need to carry my scooter on my camper van?

I need help figuring out what specific equipment I need to carry my large Honda Helix scooter on my old 1982 Dodge Xplorer 228 camper van. I'd like to carry it on the front but I'm not sure if the bike is too heavy or how to go about it. And the back of the van is extended about 5 feet so I don't think it'd be best to carry it on the rear. I'm not sure what all the info I need to figure this out but here's a little info about my van.
Its a 1982 Dodge Ram B350 that was extended and turned into a campervan.
GAWR Front: 3600 LB
GAWR Rear: 5360 LB

I don't have a hitch or anything on the front. I need to figure out which hitch is which. Thanks.

Added (1). The scooter is a Honda Helix which weighs about 350 lbs dry and is 89 inches long, while the width of my van is 75 inches wide.

Added (2). Scooter has a wheelbase of 64 inches. If that helps.

Why isn't my motorcycle starting?

I thought it was the battery, so I bought a new one and it still won't start? It was turning over then now when I hit the starter button I get nothing. The headlight dims when I press it but nothing else at all… Thoughts? 1995 Honda Shadow 1100

Is selling a motorcycle considered a business?

If I sell my motorcycle which is a Honda cafe racer custome and make a huge profit am I considered a business and have to file as a sole proprietorship and file taxes on the profits that way.
