Ok, so I checked my rear spark plug and all looked good, then figured I'd check the front. So I have to rotate the radiator to gain access, after removing most of the plastic on the bike. Well, I undid the bolt and the radiator rotates maybe an inch! So I tried loosening the remaining bolt, no difference. It's funny that you're supposed to be able to rotate the gas tank up out of the way too- but I've been stuck just removing the whole thing! Any tips to get to the plug?
