SO this weekend i finally got around to re jetting my bike and some other stuff. SOB if that spark plug is not hard as hell to get out of the 450. what gives. I even pulled my tank hoping it would help but still a pain.. i cant imagine that its even possible to pull a plug with the tank on still is it ??? you think they would give you anouther inch or so between the frame and the top of the motor. ... is there an easier way. i was just using a 5/8 spark plug socket and a 2 inch extension with a 3/8 inch rachet. i barely got the rubber boot off the top of th motor cause there was barely any clearance. there has to be an easier way or a better tool. #2 .. I didnt pull the carb all the way off the bike, too many cables to disconnect and TPS wires and hot start and all that. plus its in there so tight. i loosened up both boots an djust twisted it enough to get to the bottom of the carb to put my quickshot on and change the main jet. do you have to pull the carb all the way to get the top off to change the needle.
