Hot water in bathroom but not kitchen???

I turned off the main water line to the house to solder new shower faucet and handle set (main bathroom complete reno). After I did this I turned the water back on and now only have luke warm water in the kitchen, but I have very hot water in the ensuite bathroom?
Could it be the anti scald device in the new handle set? Maybe something else? The kitchen faucet is down stream of the new bathroom handle and faucet set if that makes any difference?????

Any idea's I am totally lost????????????

Thanks!!!!

Remove the (Kitchen faucet) HW valve or catridge and flush out the line. If that doesn't work, do the same thing with the HW stop valve.

Thanks I will try that! The kitchen still has good pressure though???

If the kitchen faucet (both hot and cold) has lower pressure, remove the aerator and clean the gunk out of it.
