Help:fitting engine kit

[Kstout]

I have beach cruiser that intend on putting a flying horse 80cc motor kit on and have a few questions about parts and fitting, this is my first motor bike build
First question: I understand I will have to mount the motor here, and I'm not sure what these two silver studs sticking out of the frame are. Would it be ok to grind these down if they are in the way of my motor?
Also on the rear tire there's a metal peice that connects from the bolt of the tire to the frame it's about 3 inches long and was wondering what this was and if it will interfere with the chain connecting to the motor to the rear wheel.
P.S. I have pictures but wasn't able to post them from my phone

I'm not sure what the silver studs you're referring to are, but the metal piece is your coaster brake arm. It may get in the way, but is easy to bend in such a way that it won't cause a problem. If you remove it you'll probably ruin the rear hub the first time you try to use the brakes.

if you are referring to the bottle mounts, I would keep them. They are handy for attaching ground wires to the frame.

I was looking into do a possibly a break conversion so I could have a rear wheel hand brake. Do you think that would be possible and if so maybe what I would need? New rear wheel and a what hand brake?

Hand operated rear brakes are a bit of a fickle thing on these, your choices are very limited to either rim brakes (not necessarily the best solution) or if you want a rear disc you need a jackshaft kit which can be pretty expensive and complicated to install. I'm not aware of another way to do a rear disc.

Hmmm interesting looked up and couldn't find anything in the forums but looked it up online. So it pretty much attaches to the top of a sprocket and can attach a brake to it? Seems simple, cheap and effective. Perfect! And if I'm wrong of what it does let me know
