Im repainting my CBR600f ('93) engine, and trying to remove carbys. I've looked in the service manual, and removed all of the insulator band screws and bands, but they are still stuck. I've tried pulling/wriggling the carbs, but the insulators (the rubber tubes) attaching the carbs wont budge up. They do move front/back, and I am pulling them on an angle while wriggling them, but they are stuck. Should I try to lever them off, or will it damage the insulators? The bike has had a hard life, and has been thrashed, so would they be cooked on?
