Who made this mid 80's to early 90's aluminum bicycle frame?

most likely a trek. Google Trek serial numbers for more info.

I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881

This is from the
Trek Aluminum Series 420 The model is TBI 0405.
Nice bicycle, but I wish they had included a chain guard as standard.
They were gray paint with a red TREK logo on the drop tube in the original finish.

The wheel is probaly to big or the frame is to little

Search engine "install front wheel on bicycle" for videos

What exactly are you needing instructions for? A bikes is a frame with a bunch of aftermarket stuff hung on it.

Everything on a bike is found on just about any other brand of bike and the individual components are usually documented at the manufacturers

Do you have a presta or schrader valve on you bike tube? A schrader is a standard valve, presta has a little nut that has to be loosened to add air. Your pump has both heads or adaptors (I don't know which model you have). You should have instructions with your pump to explain how to use it, if not go to www.ehow.com and you can read all of the instructions, no use me repeating what you can read on your own.

Look on the sidewall of your tire and see what it is rated for. Also, do not go to a gas station to fill it up, go to a bike shop and ask them or buy a bicycle pump with a gauge. Always make sure that your tire is seated on the rim evenly or you will pinch the tube and it will blow up. Car tires have more volume so that is why you cannot use the same air pressure device. Your tire will say 90-120 lbs more that likely but your tires is not that big around.

the front forks as facing the wrong way, loosen the handle bar head stem and turn the wheel and forks 1180 degrees

Can you explain why you think the tires are too big? Do they NOT fit the rims? What condition was this bike in when you bought it? If the brake pads line up with the rims then the wheels are correctly sized for the frame.

the sharp edge could be polished, but its up to you what you want to do with the ppl you ordered from. just for safety, it should be blended out, so it does not crack, thats what i do on aircraft aluminum
