I recently replaced a kitchen sink only to discover that the hot water pressure had suffered considerably. The cold water pressure hasn’t changed at all and there are no leaks to speak of. Any suggestions on how to remedy this situation?

disconnect the hot water supply at the faucet and run it into a pail to see if there is pressure,if there is then there is gunk in the cartridge.
If there is no pressure then the problem is more than likely the angle stop.
I Have checked the valves already and there is no gunk of any kind. It's a single handle system and the cold water side has excellent pressure. The hot water pressure is bad all over the house. Is it a possible hot water heater issue?
HW pressure bad all over, would be a problem at the water heater, or in the HW main, or on a rare occasion the cold feeding the HW.
When you replaced the faucet did you shut the water heater off?
Like I said earlier HW pipes are more likely to get a build up in them.
BTW this is a flow problem not a pressure problem.
To check the water heater itself is a bit time consuming, but rather easy to do if you have flex connectors on the tank.
Shut off cold water to the heater, then disconnect the flex & fill a five gallon bucket 1/2 full using the flex & time it.
Then reconnect the flex & repeat with the HW side. If there is nothing obstructing the flow, it should be real close in how long it takes to fill the bucket 1/2 way.

I would do what plumbill recommends,in his post to check for flow, what kind of shut off valve is on the W/H ? I have repaced quite a few gate valves that have failed due to corrosion and gunk build up,most of them had broken stems inside the valve body and the gate was restricting the flow.
I agree with the ex fitter.
Hot water pipes are more common than cold pipes to get scale & calcium build ups that will break free when there is an alteration to the system.
What type of faucet? Sounds like grud in one of the valves.
It's an American Standard faucet. I've taken the thing apart several times thinking it is the faucets problem but nothing looks out of place or dirty or anything.
Disconnect the feed line under the sink and try to fill a bucket of water from the line before the faucet, should have the same flow/pressure as the cold side. If not the problem is before the faucet. If this test is good then its something if the faucet.
Swap over the feed to the faucet ie turn on hot for cold.
Does the problem swap sides? If not its a faucet problem, if it does its a supply problem.
Perfect. Thanks for this advice, I will try it and move forward from there.Thanks a lot!
I ran to a problem with a Perless single lever.
They have rubber "checkvalve" in the end of each supply line. It is like an flat washer with and extended portion that goes into the tube (like a witches hat). In the exteneded portion is a slit so allow water through.
Apparently I tighted the connection up too much and whole thing was pushed into the tube and after a couple of years it worked it's way up into the valve assembly and I only had a dribble on the hot side.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
So I should loosen up the connections?
No, the stop valve connections was tight.And the piece worked it way through into the facuet.Removed the ball (Perless is the same a Delta) and used needle nose pliers to pull it out..

Once when tightening the copper tube from the faucet onto the valve it twisted on me like a piece of licorice and cut off the flow of water. Run you hand up or look a the entire length to see if it's twisted.
