Mixture screws...

I know too, but thanks for trying.

 

We wrote down the settings it came to us with so we can return it any time
we like.

What exactly would sending the bike to a mechanic teach me?

 

If flames are coming out of the exhaust or bellmouths/airbox my money's
on something being wrong.

 

Then do so. Now.

It'd get it running right. I'd suggest that if you've got flames from
the exhaust you're very likely to do the bike, and possibly yourself,
serious damage if you continue to run it like that.

As for learning - well, hopefully you've already learnt two things:

1. Don't trust your dad, he's a complete fuckwit and
2. RTFM _before_ starting a job. If you don't understand it, don't
touch it.

 

Yeah, but it looks cool.

 

We used to use wire wool in the exhausts.
