Will fuel additive kill my 06 CBR 125?

most carb cleaners added to gas work best as a maintance item, they might clean up dirty carbs,there a little rough on rubber and plastic parts, if your jets/carbs are pluged up the only good way is to pull them,clean out the float chamber,main jet,idle jet,float valve,and page ways- its a good time to change fuel lines and filters,make sure the tank and and fuel valve screen are clean...if the bike will run, you can try some cleaner,don't use to much,should be ok
