Check the petcock to make sure it's actually working. If there is a little nipple on the back of the petcock then make sure there is a line coming off of it. If there is then **** on it while the gas is on but the fuel line disconnected. If you apply 3-5 psi of pressure then the diaphragm will release and gas will flow. If not then you need a new petcock.

This sounds like no fuel flow to your carb. I would proceed as follows:
Pull fuel hose from the inlet of the carb and see if you have flow, if not, check for plugged screens. While in this step, consider draining all fuel and replace with new fuel.

If you did have fuel flow, you will need to take the carb(s) apart and see what is wrong. Some times the float needle gets stuck and a moderate tap on the carb body with a screwdriver handle sometimes releases it, otherwise, you need to open the carb and look for gummed up orifaces and inlet valve issues.

Take your carburetor apart and clean it. Paying close attention to the slow jet and slow jet passageway through the carb.

in adition to the above coment, which i must say is spot on, the posability of a used barel and piston if a new piston is not available could be worth considering, other things you may wish to check on that particular engine is camshaft seizure, in a uk bike it runs directly in the machined surface of the cylinder head, oil failure due to blocked oil filter has severe consequenses, located on the l/h side of the engine under a 22 or 24mm spaner head cap just below the gear change lever, this is a washable filter retained by a cap and spring, correct replacment is inperitive. are you located in UK? HOPE THIS HELPS YOU

Your bike will only run at full throttle if your cable or main jet needle are stuck in the full throttle position .Take your throttle cable off and check that its freely working inside the outer caseing .

Your listing is confusing ... is it a CB-100 or is it a xport 110?

In either event, I think your cable is broken. If the cable is NOT broken, it is time for a new clutch on this 33 year old veteran. You will find detailed generic instructions at the Honda Riders Club House (search Honda Rider Club). If you pay the couple bucks to join, according to information at the site, Honda will give you access to the service manual for your motorcycle.

My first bike was a CB 100 - it is one of many great bikes built by Honda.
