mine are in a similar condition,i was lucky to get a set off ebay,you cannot get pattern ones for the thou so if you want to replace them then it is either a used set,they do turn up on ebay time to time or a set from a dealer but they are not cheap,they are £43.25 each,you could try some rubber vulcanising or even some flexible petrol resistant sealer if you dont want to replace them,as to if they are affecting the running of the bike start the engine and squirt some wd40 or even carb cleaner onto the rubbers,if the engine note changes or the revs fluctuate then you have an air leak
