Phil: Inspect them, clean them with Isopryl Alcohol, clean the mating surfaces and you should be good to go. Just be aware that when you remove the covers, the rear one comes out best if you go fowards, quarter turn then out on the left side of the bike. There is a small locator pin for the gasket - one each cylinder - doesn't come out easily but watch it - could just drop in the in the valve area or worse, down the camchain shaft......for shimming, use a swivel head magnet - auto store - looks like long pen with an adjustable tension magnet...priceless!!
