The engine is making a loud noise towards the bottom of the crankcase. but when i raise the throttle it goes away

check engine oil pressure first .how is the oil pressure? is it low ?
when you raise the engine speed and bring it down to idle fast ---do you hear the noise? Do not do that at high speed and only once or twice or may do more damage to the engine. If you hear the noise ---"knocking" ---than it sounds like a loose connecting rod bearing ----means you need your engine rebuilt or replaced.

Knocking sound i only hear it inside it is a KZ 1983 7

The fuel tank will be the magnification point because of the liquid and thin sheet metal. It could be a fuel knock whick should go away at yhe bike burns off any excess.Check your oil for the order of ga and any metal content. O had a Yamafa 350 that Ran me down that road untill O discovered the fuel was free running and flooding the ctap out of a cylinder. Run the bike awhile and if it clears up, Chk tomake sure the tank petcock is not on pri. or res.If it has a three position pet **** and it is vacuum controlled, It can allow fuel to pass through the vacuum line unrestricted if the diaphram is damaged.

'99 Forester with a knocking noise at idle and acceleration

sounds like you have a headgasket blown, a head, or your rocker arms or lifters whatever you prefer to call them are running dry. might be time for oil change and coolant flush. If ther is no overheating or coolant smell than get your injectors checked. You might just have a broken seal that emits louder sound from the pulsating injectors. Good Luck!
