Cylinder 1 or 2 misfire

How would I figure out which cylinder is misfiring an how would I fix it

Check the plugs first.

Ok you think that might also fix my high rpm trubble an what am I looking for on the plug an then what do I do

Pics of the plugs and tell us what you've done with the bike.
Steve

I've rebuilt carbs then been clean and I changed the sprockets I'll get pics after school tomorrow

How do you know the misfire is with #1 or #2?

Engine cold >>> after starting the engine, pat the exhaust pipes to see if they're warming up evenly.
After the engine is warmed up, use a spray bottle to mist the pipes --- the water should sizzle.
Don't get burned --- don't touch the pipes when they're hot or starting to get hot.

Battery. what's the condition of the battery? the bike needs a good, fully charged battery to run right as it provides the energy to fire the coils. I use a Ctek US 0.8 smart charger & VC97 digital multimeter.

Ignition system. Any idea if your bike has the original ignition coils? The stock coils can be problematic, especially since the spark plug wires are molded into them. If the coils are old, they may need replacing. but maybe not. and new spark plug wires. Check, clean & lubricate the timing advancer. be sure to separate the rotor from the body so that it can be properly serviced.

Was it missing before the carbs were cleaned?

Heres the pic soark plug

Yes it was

How would i cheek the ignition system

Do you have a manual?
