Honda Question

[BlackHat2305]

i own a 2000 honda 600 f4 , bike has just hit 10k miles . the bike runs great except when not in gear and the throttle is cracked it sounds like the bike is breaking up . now im not sure if the gas i recived was bad or not , but the breaking up was noticed after i got gas. I wanted to check my plugs to see weather or not they were fouled so revoved the fuel tank and air intake and tried to take the plugs out but it was a no go as honda has a support bar accros the cylinders and i could not get the spark plug socket in the hole even with diffrent extensions . do they make a special tool for removing the plugs ? any help is appricated and also i wanted to add some carb and fuel injetor cleaner to the fuel is that a good idea or no ? thanks for the help
