I've tried this method using card board paper from a card board box and indeed it does reduce engine noise however; when riding for a while and the engine gets really hot it starts smoking and burns the card board paper. I'm assuming using this rubber piece will do the same. Any restriction on the engine fins will cause faster heat and will result smokey hot engine!
