I just replaced the front brake disc and pads on my bike, but it makes a clak noise that stops when I slightly pull the brake lever.
Does anyone know what is wrong?

-Yes, year, make, and model will help -A LOT! A very common problem, which can/does cause various odd noises is the piston binding in the caliper. First, lift the wheel clear of the ground, see if it spins freely. Apply brake, then release -see if it still does. If not, take a couple of screw drivers, and from each side, push the piston back into the caliper. It should move, but does require some pressure. Then apply the brake, see what now occurs. If it does not move, bet a rebuild kit for the caliper, be sure to clean EVERYTHING completely. lube with brake fluid and reassemble. If everything appears to be in order, make sure you have no parts missing, such as a damper spring or pad, used on some brakes, then ride it a bit. Sometimes it just takes a few miles for new pads to settle in.

Another thought - after reading your post again, I am thinking that you likely left out the spring retainers which locate and support the pads in the calipers. Different bikes use different approaches to doing this, but all do it in some way. The purpose is to keep the pads stable in the calipers, when the brake is not applied. Sometimes these things can be a real pain in getting the caliper back over the disk, and lined up to be bolted in. Just something to think about.

Some discs are solid mounted, others float. Since bikes (motorcycles that is) are sometimes "cutting edge" in technical areas and often in brakes, you may have a disc that floats. My guess is that you did something wrong when you reassembled the brakes, and it's probably in the disc rather than the pads.
It could even be in the new parts you installed. The new disc may not be correct in the tolerances where the floatation interface is and you're getting some slop that clatters around until you clamp on the binders, then it's pressed against the post and stops making noise.
Did you have parts left over after you replaced the old disc? Perhaps there were some sleeves on the old disc that didn't get transfered over onto the new disc.
Hope you get it figured out, your brakes are your ticket to additional days on the planet.

You may have a warped disc, that is slapping the pad every revolution. Raise the front off the ground , and slowly turn the wheel 360 degrees. Look at the brake pads as its turning to see if the disc moves in and contacts the pad. It could also be a sticking piston.

Did you upgrade to a floating rotor? If you did, the noise is normal. It bothered me at first because it was different, and I don't like that extra 1/2 second before engagement, but I got used to it pretty quick.
If you did not change what kind of rotor you have, there is a problem that needs to be taken care of quickly. Take it all apart, and make sure you got it together correctly. Can't say more without knowing more about your bike.

Always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer.
All I can suggest at this moment is to double check your work. You might have left a part out by mistake. Jap bikes have a "spring" (flexible sheet metal) to keep pressure on the pads
