Rattling noise in dirtbike engine?

I posted here the other day and I'm back with new info and updates.

I did an oil change that didn't help, the oil was low so I was hoping that would fix it

I don't know what it is, its in the engine though, I uploaded a youtube video so you could hear it, the metal rattling sound isn't as bad in real life as it is in the video but the camera picks it up easier but it makes it easier for the camera to hear.

Please help, what the issue is or could be thank you

Added (1). Also dirtbike is a 2009 Honda Crf100F

Can't find cheap insurance for m1 license?

I live in ontario and i just got my m1. I'm planning to buy a small motorcycle just for going to school (honda grom 125cc). However i can't find cheap insurance for it. The lowest quote that i can find so far is around 3100$. Does anyone know any place that i can find a better deal?

I want to buy a 125 cc bike or scooter like activa which is equivalent to 125cc. Which one is good?

My specifications are:
tube less tyres
should have a carrier or pouch
should have anti theft option.
more mileage more cc

My preference is of honda shine but it doesn't contain some of the options. What about mahindra etc… Please give detailed answer

Added (1). I don't want digital speedometer it doesnot work…

Added (2). only please answer this…
if its scooter which is best in india
and if its 125cc bike which model of honda shine is best?

What motorcycle should i get? - 1

So, i just got finished the endorsement class required for WA state. I want to buy a motorcycle, for around 2,000. I'm thinking a cruiser-thats what i rode in the class a suzuki 250. Any recommendations for a bike in my price range, 250cc or so, and i'm leaning toward a cruiser, although i had never ridden before the class.
Something along the lines of a honda rebel? Any advice? Also, i'm a bit nervousabout buying/test drivng one, i kind of want to practice some more-back roads etc, before taking to the street. If i were to buy at a shop, do places do delivery?

Are cruisers better to start out on particularly the 1999 honda magna?

My dad (who has only ridden a 250cc honda scooter than upgradded to a 1993 CBR1000F back in the day and is now going to get but hasn't ridden a honda CBR650F) thinks I should get a 300cc beginner sports bike but the problem with that is that their too new and too expensive I would not be against getting a Hyosung gt250r or kawasaki ninja 250 but I also want to be able to do 1000 mile trips on it and my brothers kawasaki ninja 300 does about 8,000-8,500 rpm doing 70mph in 6th gear so I don't want my 250 on a long highway trip sit at an rpm thats too high for too long (on the road 10 hours a day). Cruisers I believe are easier to control so what are your thoughts on starting out on a 750cc V4 Magna or do you have a different suggestions for a beginner motorcycle. (note my budget is $3,000)

Dirtbike engine making a clanking kinda sound?

Its a honda crf100f, when, i start it, its fine, but when I go to rev it, and the rpms get higher, there's a metal sound in there, not really sure how to describe it, like a really fast vibration sorta, but its metal on metal, could low oil cause that?

I haven't done an, oil change for 6 mobths but the oil is still clean in it and I forgot what kind of oil it took.

Should I get a 50cc or a 125cc bike?

I'm 17 and need some transport on a budget - I'll be commuting in and around towns, for about 60-80 miles per week. I'm aware of the speed differences between the 50cc and 125cc, but will it be a big factor if I avoid motorways?

Also, does anyone have any advice on models? I obviously want to avoid cheap Chinese copies, but it's hard to find reviews for 50cc bikes.

And then the Honda CB125 seemed good in terms of the 125ccs… Thoughts?
