Try bleeding the cooling system of possible trapped air as described in the service manual.

You also might want to check the plugs and wires and to check whether the ignition timing is set to spec.

alright guys, i noticed that my water coolant housing cover was cracked so i replaced it today, bled the coolant, refilled, bled again, refilled, checked timing, adjusted idle [manual procedure], and now it runs pretty good, im going to bleed the coolant some more again to make sure there isnt any trapped air, also getting new spark plugs tomorrow, but theres one thing since i adjusted the idle screw alot to let more air in it seems like my intake is sucking alot of air in and i hear loud hissing is that normal? my idle is perfect now and everything....

Hissing from the intake is normal if you don't have one of the lines in or if you have the intake tube off.
