In general trying to lighten a bicycle isn't particularly cost effective. Bike parts are much more expensive bought piecemeal than bought as a complete bike. But is you insist the best way to go about is is to dissassemble your bike, weigh the parts (seat post, saddle, cranks, forks etc etc) and then replace them one by one with lighter parts.
NOOOO! Do not make that mistake!! A lighter bike is a better bike. I own a Specialized FSR Comp that weighs about 30lbs, but I'll probably lighten it. Lighter bikes are much easier to uphill as well.
bigger cyliders, bore out the engine, make it lighter
To make a bike go faster, you can pedal harder and faster, reduce wind resistance by tucking in your body, use a lighter bike, maintain proper tire pressure, and ensure your bike is well-maintained.

You replace part by part with lighter and more expensive parts. usually not a particularly sensible thing to do as bike components bought piecemeal are much more expensive than when bought as a complete bike.
Simply change the exponents on the bike for lighter ones, like the wheels, tires, seat post etc. this will cost more.
Considering bike frame weight is important when choosing a new bicycle because a lighter frame can make the bike easier to handle, accelerate faster, and climb hills more efficiently. A lighter frame can also reduce overall bike weight, making it easier to transport and maneuver.
if you want it to go faster with no performance parts you will need a lighter person
To make your bike faster, you can upgrade to lighter and more aerodynamic components, maintain proper tire pressure, adjust your riding position for better aerodynamics, and regularly clean and lubricate the chain and gears.
A street bike is a type of BMX bike, so your question can't be answered.
As a general rule if two bikes are in the same price range, the smaller of the two will be lighter. This because there is less material used in the smaller BMX due to it's much simpler construction. But, when you head for the high end, a flatland or racing bike is going to be much lighter compared to a mountain bike.
